I asked what others did for benchmarking in my last post. Here are the replies on Twitter in a semi-coherent edited form. If I missed any replies, I blame Twitter, whose interface is a magical maze.
First there were some FPS vs. SPF comments:
Richard Mitton: If you’re not measuring in milliseconds then you’re doing it wrong.
Christer Ericson: Yes, ms, not FPS. FPS is not a linear unit for the artists (or anyone).
Marc Olano: FPS isn’t linear. Usual definition of median averages middle 2 for even samples = also wrong. Use ms.
Morgan McGuire notes: FPS *is* a good measure if what you care about is interaction or visual smoothness. SPF is good for computational efficiency.
I replied to Richard & Christer: I’m interested in your reaction to the use of median vs. mean. FPS vs. SPF irrelevant for relative performance.
I also changed the original post to talk about milliseconds instead of frames, to avoid this facet of the discussion.
Christer Ericson: It’s important to catch the spikes, so in the context you’re talking about I would do max. Or mean+variance. Also, don’t think I’ve ever, for profiling reasons, looked at any average. You always look at a specific frame.
Timothy Lottes: I’m personally only interested in worst case ms/frame.
Cass Everitt: Agree with those that concentrate on worst times.
Eric Haines: Right, it depends what you’re looking for, e.g. don’t drop below 60 FPS. I’m mostly warning against using mean.
I added a note to the original post about tracking the max, which makes sense if you’re trying to guarantee a frame rate.
Tobias Berghoff, who benchmarks consoles:
I use min/max/med the most. Averages really only come into play when I need more digits. I spend significant amount of time below the 0.5% mark when wearing my platform tuning hat. I don’t miss trying to get sensible numbers out of PC h/w. But this also comes into play when measuring very short processes. When something only takes a couple of microseconds, you often end up oscillating between states that make the distribution multi-modal. Median won’t catch small shifts.
cupe: Stacked color-coded graph of nested timings (or a subtree of it). Usually unfiltered for analysis, avg for comparisons. Hierarchy is on the left, tooltip displays e.g. “scene/fluid/poisson”, click to restrict. Horizontal lines are milliseconds, orange line is 16.6 ms.
E.g. click the big violet bar to see only post (and zoom in to stretch 4ms to screen):
Javdev: We use a profiler, Adobe Scout, select multiple frames & see which code is most expensive & iterate it to prevent frame drops.
Björn Blissing: One option is to plot a histogram over the captured data. Reveals if your max/min are outliers or more common occurrences.
Michael Marcin: Try always running circular etwtrace and when frame time dips save and examine the trace.
Mikkel Gjoel: We filter in viewer. Options for all mentioned, and vsync (as that is what we are shipping).
Fabian Giesen: General order statistics (percentiles etc.) are good. Just a plot of frame durations over frame # is helpful, too! And simply recording all frame durations over a few seconds, sorting them and plotting that is quite handy, too. That gives you all the percentiles (and median etc.) and gives you a feel for the shape of the distribution, which matters. (I’m not very happy with single-value summaries; they lose too much information.)
Jaume Sanchez Elias: I like Chrome FPS meter: current, min, max; over time; frequency graph for each framerate
Krzysztof Narkowicz: Min, max, avg and std dev. Percentiles and med would make a nice addition, but it’s a hassle to compute them.
Anton the Mighty: I always use the standard deviation or standard error and indicated what value n sample size is. Most gfx benchs=bad. It’s usually worth also eyeballing actual data in detail because repeating patterns show either cycles or error in timers. Most recently there was something a friend had with the power manager in windows causing a cycling load on the cpu. I also visually check out timing for cpu+gpu functions across frames with apitrace etc. pretty neat.

The following is a recap of major events in the world of game development for the week ending April 17th, 2016. I do a weekly video recapping the news available here with this week’s video embedded below. This post is a collection of links mentioned in the recap.
The whole idea of Kraken is to excel in the size-decodespeed tradeoff. From the beginning of its design, every decision was considered in terms of the size vs decodespeed.
So how does it do?
To visualize the size-decodespeed Pareto frontier, I like to use an imaginary loading problem. You want to load compressed data and then decompress it. One option is the null compressor (or "memcpy") that just loads uncompressed data and then memcpys it. Or you can use compressors that give smaller file sizes, thus quicker loads, but take more time to decompress. By dialing the virtual disk speed, you can see which compressor is best at different tradeoffs of space vs. speed.
Of course you may not actually be just trying to optimize load time, but you can still use this imaginary loading problem as a way to study the space-speed tradeoff. If you care more about size, you look at lower imaginary disk speeds, if you core more about CPU use, you look at higher imaginary disk speeds.
I like to show "speedup" which is the factor of increase in speed using a certain compressor to do load+decomp vs. the baseline (memcpy). So the left hand y-intercepts (disk speed -> 0) show the compression ratio, and the right hand y-intercepts side show the decompression speed (disk speed -> inf), and in between shows the tradeoff. (By "show" I mean "is linearly proportional to, so you can actually look at the ratio of Y-intercepts in the Pareto curve and it tells you compression ratio on the left and decompression speed on the right).
The chart showing "millis" shows time, so obviously lower is better. I show a few ways to combine load & decomp. Sum is the time to load then decomp sequentially. Max is the larger of the two, which is the time if they were perfectly overlapped (not usually possible). Personally I think "l2 sum" is most useful. This is the sqrt of sum of squares, which is a kind of sum that biases towards the larger; it's kind of like a mix of "sum" and "max", it means you want the sum to be small, but you also want them to similar times.
Kraken tops the Pareto curve for decodespeed vs size for a huge range of virtual disk speed; from around 2 mb/s up to around 300 mb/s.
Of course the Pareto curve doesn't tell the whole picture. For one thing I don't have encode speed in the equation here at all (and sometimes you need to look at the memory use tradeoff too, so it's really a size-decodespeed-encodespeed-memoryuse surface). For another you sometimes have strict requirements, like I must hit a certain file size, and then you just pick the fastest decoder that meets that requirement. One thing the curves do clearly tell you is when a curve just completely covers another (that is, is greater in Y for all values of X), then that compressor is just never needed (in space & decodespeed).
Game Test Set :
Just for comparison to earlier posts on my Blog about the other Oodle compressors, here's a run of lzt99 with the full Oodle compressor set.
I've included ZStd for reference here just to show that Kraken jumping way up is not because the previous Oodle compressors were bad - far from it, they were already Pareto optimal. (I like to compare against ZStd not because it's bad, but because it's excellent; it's the only other compressor in the world I know of that's even close to Oodle in terms of good compression ratio and high speed (ZStd also has nice super-fast encode speeds, and it's targetted slightly differently, it's better on text and Oodle is better on binary, it's not a direct apples comparison)).
You can see that LZHLW is just completely covered by Kraken, and so is now deprecated in Oodle. Even LZNIB and BitKnit are barely peeking out of the curve, so the range where they are the right answer is greatly reduced to more specialized needs. (for example BitKnit still romps on strongly structured data, and is useful if you just need a size smaller than Kraken)

TexturePacker is a handy tool I’ve featured several times here on GameFromScratch as well as a video feature as part of the gamedev toolbox series. It’s one of those handy Swiss army style tools that enables you to pack multiple images into one or more sprite sheets. Texture Packer 4.2 brings a number of new features to the table:
- a simplified user interface is available now for new users
- improved help
- indexed PNG (PNG-8) (more) available
- improved sprite sheet animation previewer
- support for ETC2, PVRTCII, DXT1/5 formats
- user interface cleanup
- several fixes
- all data formats now use UTF-8
- EaselJS/CreateJS animation frames now written correctly
- now case sensitive aware on MacOS
- better Cocos2d-x support
It was only a few months back that Amazon launched Lumberyard, their CryEngine powered game engine. In March they released Lumberyard 1.1 then earlier this week they just released Lumberyard 1.2. At least out of the gate they are keep the updates coming at a good pace.
So what exactly is in Lumberyard 1.2?
- new audio tutorial on integrating Wwise audio in Lumberyard
- extended mobile support from 1.1. More iOS and Android devices added included iPhone 6 series, Air2 and iPad Pro, with Note 5 and Nexus 6 added on the Android side )
- network bindings for components enabling network synchronization
- improve particle editor including library support, GPU particle rendering, advanced playback controls, a gradient editor and more
- UI Animation system enabling you to animate certain properties of UI components.
That’s the new features, then comes the rather massive list of changes and features.
• The Asset Processor now stores log files in a logs subfolder (located in the same location as
the Asset Processor executable file). These logs include detailed information that you can use to
diagnose issues in the Asset Processor.
• The Asset Processor now recognizes when copies of the tool are stored in different locations for
different projects on the same machine. If you attempt to run Lumberyard Editor while the
Asset Processor from a different branch or version of Lumberyard is running, you will receive
notification and the option to run the correct Asset Processor or exit the old version. This helps
to prevent connection to and communication with the incorrect Asset Processor.
• To allow you to get started while assets compile in the background, the Asset Processor now
supports priorities assigned to asset types to compile in the configuration file. By default
meshes and animations are preferred over textures.
• A new algorithm is now used to order the Asset Processor’s build queue and dynamically
reorder the queue based on the connected platforms and the assets requested by these
platforms. Unconnected platforms have a lower priority than connected ones.
• The default audio error logging verbosity is now set to Errors & Warnings to increase visibility.
• Added a flow graph node to control Audio components.
• Added a method to stop all sounds to the audio proxy.
CLOUD CANVAS RESOURCE MANAGEMENT
• To help reduce confusion about their purpose, removed the Development deployment and
Hello World feature from the default project.
• Deployment stacks are no longer created under the project stack. This change allows you to
create, update, and delete deployments without risking changes to other deployments.
COMPONENT ENTITY SYSTEM
• Added the ability to push unrelated entities with instanced entities to a slice asset.
• The Entity Outliner can now show multiple components of the same type.
• The FBX Importer now automatically converts FBX units to meters. This allows you to use scenes
from different content creation packages because the content is automatically scaled logically
• The FBX Importer now reads Up-Axis orientation data. This allows you to use scenes from
different content creation packages because the content is automatically oriented logically
• Changed the command that is used to start the Amazon GameLift server from start_lobby
• Added support for idle timeout in all modes. Idle timeout is disabled by default. To enable idle
timeout for Amazon GameLift, you can add +sv_idle_seconds 600 to your server’s
command line in the Amazon GameLift dashboard.
• Removed the GridMateGameLift static library and moved all Amazon GameLift code in the
Multiplayer Project to the Amazon GameLift Gem.
• Changed the include paths for Amazon GameLift session header files from
GridMateGameLift/Session/.. to GameLift/Session/...

modular approach, allowing you to more easily customize the engine for your needs. You can
optionally include this Gem in your Lumberyard game project.
• Disabled the Connect and Host flow graph nodes for the Multiplayer Gem.
• Added the ability to search for Amazon GameLift sessions by game instance ID. This enables
you to create a custom matchmaking service with your game hosted by Amazon GameLift.
• Added support to the GridMate API for reusing EC2 instances in Amazon GameLift, which
removes the need to spin up a new instance for every game session.
• Modified replica initialization to take a debug name.
• Updated AzFramework to require GridMate. On Xbox, GridMate requires winsock
(ws2_32.lib) to link in. On Windows, GridMate links in using a pragma in code.
• Removed support for Windows XP and earlier by updating the _WIN32_WINNT version to
0x6000 (Windows Vista), and removing the unnecessary inet_ntop() implementation.
• Modified UpdateFromChunk to call per chunk and not per replica.
PROJECT CONFIGURATOR – Various updates include adding metrics reporting, ensuring the
ProjectConfigurator.log file is saved to the engine root, and updating the project template to
match the latest changes to the Empty Template.
• The Twitch:JoinIn:CreateLink flow graph node now includes an Error port, which is
signaled if the link was not created successfully. The GameName port was removed; the game
name is now copied from the sys_game_name console variable.
• You can now use the joinin_uriScheme console variable to set the URI scheme for the
JoinIn link. The default value is game.
• You can now use the chatPlay_GroupServerList console variable to set the list of group
chat servers and ports.

now located at the top of the pane.
• Added the ability to remove components by right-clicking the component.
• Added the flow graph nodes Ui:Element:SetIsEnabled and
• Added the image types Stretched to Fit and Stretched to Fill to the Image component. These
image types maintain the aspect ratio of the texture when the element is a different aspect
• You can now show the anchor preset in use by using the icon to the right of the anchor values
in the Anchor properties.
• Renamed the following parts of EBus for clarity:
o EBusEventGroupContainerTypes renamed to EBusHandlerPolicy
o EBBCT_SINGLE renamed to EBusHandlerPolicy::Single
o EBBCT_MULTI renamed to EBusHandlerPolicy::Multiple
o EBBCT_MULTI_ORD renamed to EBusHandlerPolicy::MultipleAndOrdered
