Radeon Linux OpenGL Driver Continues Giving Its Best Against Windows 10

[dungeon]

Okay, how many people here can run observer on r600g with current Mesa and don't get GPU lockup? Anyone?

How much you expect people to play that on TS hardware when:
System Requirements - Minimum

Windows:

NVIDIA GeForce 660 / AMD R9 270

Linux

NVIDIA GeForce GT 680

Your mobile Radeon HD 6650M only have bigger number there, but is really older than these minimum required ones.

Even here we could see that Linux game ports usually require a class more GPU hardware for the same results

Unrelated, anyone expect driver to not lock up GPU.

By the way, I have exactly same issue on r600g, any ideas why it could be?
Seems like LLVM patch is amdgpu-specific, and LLVM shouldn't be matter for r600g at all, yet exactly same behaviour for some reason.

You probably should bisecting if it was working before. Chances Dave can fix this are way higher then.


Edit: BTW, Shadow of Mordor just got an update:

Wonder what was fixed...

Thanks! These are great tests. OpenGL vs OpenGL head to head is interesting but the DirectX vs OpenGL very clearly demonstrates the "What you would get if playing in Windows" vs "What you would get if playing in Linux" because lets be honest, no one games on OpenGL on Windows if DirectX is an option. And the games where OpenGL is the "only" option, it is generally optimized enough (Doom 2016), but are rarer, and don't necessarily get Linux ports anyway.

OGL v OGL only shows thats Linux OpenGL drivers are good enough. But that means nothing if games are still only written in DirectX. Same holds true for Vulkan. Even if linux performs the same or better in vulkan, it doesn't matter if games don't use it. The potential for Linux gaming performance is amazing right now, but DirectX is some real vendor lock in.

With this performance difference I can see why feral dropped phenom II support on Linux which is playable on windows. A person on on youtube running Deus ex Mankind Divided. A AMD Radeon R9 280X and Phenom II x4 965 BE DX11 running at stock speeds, the lowest fps was 27 in a fire fight. He could of overclocked and got a bit more performance.

Does that game work for you on Windows or maybe using FGLRX on Linux for example on that HD 6650M?

Looks related to me, since they wrote newer gen hardware minimum required there even for Windows.

And GRID Autosport; now I remember I seen same video playback issue in GRID Autosport too, and even reported it to Feral.

Unrelated to r600g driver issue.

Good tests Michael. Stopped doing DotA testing?
wonder if there are any unreal engine games with automated testing capabilities.

Too bad the Feral ports all perform that bad - they are barely useful for benchmarking :/

Except that the Feral ports are real games that real people actually want to play... My boys have had great fun playing Mad Max, Tomb Raider, Hitman, DiRT Rally and GRID on their Ubuntu computers with good-enough performance on their Radeon GCN GPUs. Who cares about OpenArena and Unigine Valley in real life?

Synthetic benchmarks are good for technical evaluation of graphics drivers, but having benchmarks of interesting and contemporary games is a big reason why I support Phoronix. Making Linux ports of major game titles, supporting Linux graphics driver development, promoting Vulkan and making their games benchmark friendly is a big reason why I buy Feral games.

We are getting there :-)

Not relevant.

These minimum reqs are there for one reason:

For ensuring some performance level.

A gpu hardlock is unexpected if you have way below minimum reqs. Only thing that you will notice , it will run at 10 fps instead of 60.
