18-GPU NVIDIA/AMD Linux Comparison Of BioShock: Infinite

[stqn]

The benchmark mode results much higher frame rates than actual gameplay. Try it and you'll see.

Agreed, I?m not sure what that benchmark displays, but in Ultra I?m getting 21 FPS on the options screen on my i5 + GTX 660! And here it says the GTX 650 is getting 77 FPS?

How can I run the benchmark without using the phoronix test suite?

From what I've read in Mantle/Vulkan, and Directx 12 specs/docs, it's most likely API calls.

Edit: Also, NVidia hits a stone wall at 127 fps

Yeah, I think it's just that modern games do a lot of draw calls, and they are dead slow in fglrx.

NVidia being about 2.5 times faster at that sounds just about right.

You can add following parameters to BioShock Infinity launch options in Steam:

DefaultPCBenchmarkMap.xcmap -unattended -resx=1920 -resy=1080 -ForceCompatLevel=2 -benchmarkfile=Test-%GPU%.csv

where:
ForceCompatLevel=1 - Your current settings
ForceCompatLevel=7 - Ultra settings
ForceCompatLevel=2 - Low settings

major issues with this game are ongoing

i reported issue on Friday, provided all details devs asked me to provide, still no reply quite yet.
I am not sure they will do anything about issues I have: http://steamcommunity.com/app/8870/d...1364599930277/

Did you turn off vsync with nvidia-settings? That's a non permantent change until you run "nvidia-settings -l" on startup (as user). Also best run the benchmark mode, it disables sound.

Thanks! I?m getting the same FPS (88) with ForceCompatLevel=2 and ForceCompatLevel=7. Also no obvious difference in picture quality. I think the benchmark is running on low settings all the time.

That sounds like fglrx performance might be just fine for the game

Yes, fglrx issue on nvidia cards... You've just made the stupidest forum post of this month.

There might not be perf issue with fglrx when someone play a game i said that i guess, because you said benchmark and actual game performance differ == If it differ for nvidia it will differ for fglrx too

It seems there might be a need for rerun of these benches with corrections, if they are possible.

I somehow doubt that any NVIDIA card runs this at over 60 FPS on Ultra at 1600p.

I have a Core i7 2600K 4.7 Ghz
NVIDIA GTX 580 with BIOS overclock to 900 Mhz.
This should be at least equal to a GTX 680.

I run this game at 1440p and on the Ultra preset it drops to 24 FPS even in the menu. I can crank everything up unless it isn't dynamic shadows and ambient occulsion, which absolutely destroys framerates for me. I have dynamics shadows at High and Ambient Occulusion at Low, to play it at around 50-60 FPS.

I also tested turning of __GL_THREADED_OPTIMIZATIONS=1 in the startup script that it uses. This absolutely changes nothing in terms of framerates.

Maybe this game favors the later NVIDIA chips. Usually games perform well on NVIDIA no matter which chip and the framerates represent actually differences in hardware power.

the benchmark mode runs faster, caus it has no sound, no npcs, etc.
