[Radeon HD 7850] Steam can't detect memory video
Hello, with my HIS AMD Radeon HD 7850 Turbo, and Ubuntu 12.10 64bits with Catalyst 12.11 beta 11 drivers, (and other stable), steam does not detect the memory video of the graphic card.

This causes a bug in Big Picture Mode, at the first launch, it's run in slow résolution, 1066x600 and big picture option detect 1.02kb of memory video.

Same here on XFX 5770, ubuntu 12.10 & amd 12.10 drivers.
Beelzebud 12/dez/2012 às 2:27 
Same thing on 12.04, 5770, 12.11 beta 11 drivers. I don't have any performance issues, as long as anti-aliasing is off, so I assume this is just a cosmetic issue in the UI.
SgtBilko 12/dez/2012 às 6:03 
My specs listed below for reference. Big Picture runs dog slow for me, I had presumed that to be due to being on AMD 12.10 drivers not the 12.11 beta driver. Note that this is after today's update.

Same problem here with HD 7850 and AMD 12.10 driver (Ubuntu 12.04 LTS 64 bits) : Big picture detects only 268,44 MB of video memory while I have 2GB :

This problem exists with the free source Radeon driver, too.

still not fixed

Welcome to dealing with Valve. Enjoy waiting forever for an issue they've forgotten exists and have no way of being reminded about.

I think it may be and AMD problem but still it bugs the ♥♥♥♥ out of me, well at least we can play most games under linux fine
LOLCAT 9 de ago às 1:26 
It probably isn't a Valve issue, but AMD. The same problem existed under windows as well for so many years. It was fixed after people started bugging AMD about it (after Rage was released). Do the same, keep submitting bug reports: http://www.amd.com/linuxreport

There is AFAIK no unified way of determing VRAM, that's why the GLX_MESA_query_renderer OpenGL extension was introduced last year. The free drivers do already support it, but it seems Steam is not using it, yet.

As VRAM is only being accessed through a MMU, one can only get the size of the memory window being used without directly interacting with the driver.
Pocket 9 de ago às 11:05 
Interesting. Last I checked, running lspci doesn't detect VRAM either; would it make sense for it to be updated to use that OpenGL extension as well, so there's a system-level way to check your specs?

Just as I said: lspci only provides general memory information about the PCI bus. However, VRAM is usually way too large to be fully addressable, so a MMU is used, which provides a fixed size window (usually: 256MiB) that can be moved across the whole VRAM to access the whole memory space. However, as the driver is the only one who controls the MMU, you can't guess VRAM size solely on PCI information.
Pocket 8 de out às 11:24 
Hang on, something just occurred to me. If there was never a way to detect VRAM until this OpenGL extension was introduced, does this mean no Linux game or app has ever been able to address VRAM at all until recently?
Letalis Sonus 8 de out às 13:23 
The drivers take care of everything concerning allocating and adressing VRAM, that's not really something any program has to worry about.

It's all just about how to get the total amount of VRAM available, e.g. to make certain guesses on which graphics settings should be disabled by default in a game. Pretty much every driver has provided that piece of information before, but everyone did it in its own way. The only place where you'll pretty much always find those values are the kernel and/or X logs, but it's hard to parse them out of there in a unified way.
