Odd, I thought #1140 would have cured the memory detection problems.
Based on referenced issue I also ran lspci

Not sure if that is part of the problem as my card has 6GB of RAM.
Ha, that's the exact same amount it's telling me I have, and I have a Radeon HD 4850 with 1 GB.
You know, this might explain why we're getting such poor performance from Valve's games, if the system can only use a quarter gigabyte of our video memory...
EDIT: lshw and lspci both report only 256 megs of video memory for me as well, so whatever's going on is probably not limited to the Steam client.
@boombatower Where on AMD's site did you cross-post this? I'm registered there and I wanted to weigh in on this.
Never really got much of a response, although it wasn't that good of a post.
http://devgurus.amd.com/thread/160348 (linked above)
Just updated to 13.4 driver and still seeing this same issue.
+1, AMD Catalyst 13.4, AMD Radeon HD 7660G, Opensuse 12.3
It might help to know that pulling up System Information tells me "Primary VRAM Not Detected". I dunno, is that the graphics driver's problem, or something with Linux itself? As far as I know, the graphics driver only concerns the GPU, but it might be going through that to find out how much VRAM I have.
Im thinking that the VRAM not being detected is a major performance concern...
Its probably the reason why I can run all settings high in TF2 windows, but I have to run all settings at min TF2 windows to get no input lag...
I can confirm this is still happening as well with 13.4. I bumped amd thread.
Im not trying to bump this, but you can set your video ram inside xorg.conf in the devices section like:
/etc/X11/xorg.conf
Section "Device"
Driver "radeon" # or whichever other driver you use
VideoRam 32768 # 32 MB
#other stuff
EndSection
@kylescottmcgill Out of curiosity, will that do anything to improve performance issues caused by games failing to detect VRAM, or will it just make lshw and lspci report the correct values?
@stevethepocket I will admit, i haven't attempted to play anything on Linux with Steam but will give it a go later on tonight. But what i can confirm is that with more resources being reported, more resources are being used, and limitations such as the above are also lifted. Keep in mind YMMV when dealing with these sorts of things. I will report back later with some results.
OK, I think I have a development. Apparently neither lspci nor lshw are supposed to report VRAM; for that, we have to pull up /var/log/Xorg.0.log and look for "Video RAM". Sure enough, we have these lines:
[ 15.709] (--) fglrx(0): Video RAM: 1048576 kByte, Type: GDDR3
[ 15.709] (II) fglrx(0): Video RAM override, using 1024000 kB instead of 1048576 kB
The second line is because I tried that trick @kylescottmcgill mentioned, using "1024000" because I wasn't sure if a gigabyte meant 1024 times 1024 or not in this case.
The problem, then, would seem to be with Steam, not the driver, if X can accurately gauge the VRAM size.
I also experience this issue. Both with fglrx drivers on HD7850 and open source radeon driver for HD5650
Same with my ATI HD4770 with OSS driver, Steam can't detect VRAM, Big Picture reports 256MB although my card has 512MB.
I'm having the vram issue now, is there a fix yet?
I know this much; it's not caused by the Radeon driver. Steam still reports this after removing it and upgrading to the latest open source driver.
I'd just like to be able to get reasonable fps, say 60? I have dual radeon R9 270 in crossfire.

From the Steam community:
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.
So apparently this would be an easy fix if Valve were still paying attention to bug reports. I assume the same fix would have to be done on their games as well.
hmm, so Valve no longer reads this?
so, devs, any news? at least let me set my own ram?
I only see 256 Mb of available RAM however drivers are installed. The GPU's an AMD Radeon HD 7730 M dualed with an Intel HD 4000 (selected GPU is the Radeon) and the drivers are installed using additional drivers provided with Ubuntu.
That is all that is available until they fix this. The drivers have been amended to allow the proper detection of ram. Steam is slow to update. Or completely ignorant of this topic.
Weird indeed. Related to the source 2 engine port to steam overlay port? (good guess)
I will note that neither the nvidia binary driver nor fglrx implement GLX_MESA_query_renderer support. This is unfortunate, as it would be most useful.
Using lspci for VRAM detection hasn't worked for a long time. Graphics cards only map portions of VRAM through an aperture, and the only thing lspci will tell you is the size of this aperture.
NVIDIA VRAM DETECTED! ubuntu with asus 960 card. my r9 270's are going in the garbage! lol

Nothing new I suppose.
same error here, 268.44Mb on Radeon 5450 with 512Mb
As noted elsewhere, this appears to be strictly a cosmetic issue, this message does not affect the amount of video memory available to games or reduce performance.
thanks
That was not my experience. I had two ati video cards that should have overpowered the nvidia 970 I replaced them with. Instead I now have smooth graphics at any framerate.
A lot more variables than just the VRAM. I an see how much VRAM games / steam uses and it's more than it detects. Still given people may have that impressions...these are the polish things that make people feel like they are using something solid.
I'm getting the same message on a HD 6950 with Catalyst 15.302 on Linux Mint 17.3 The card shows 1024mb vram in Catalyst Control Center, but Steam detects only 260
I experience this too, and it does have an effect on performance. I have amd r9 390 wth 8Gb, and steam detects 256Mb. The rest: amd fx8350, 16Gb ram, asus crosshair v formula z. Linux mint 17.3 cinnamon, driver fglrx 15.302. I'm (maybe because of this) unable to set the resolution to my native 1440p, and the game then runs at a lower resolution, plus the steam big picture is partially outside of my screen, unaccessible. The game, cities-skylines, runs at 14 fps. This is too low for the hardware i have.
Did we ever get a fix for this? I get this warning in Big Picture and I get very noticeable input lag just navigating the Big Picture menus using the Steam Link to stream from a Linux host. This host is running Fedora 23 with an AMD R9 270 on Mesa 11.1.0. If I boot the same machine into Windows10 the lag goes away.
I still get the message, even with my new card that the System Information dialog correctly identifies as having 2GB (in Windows it says I have -2GB, which is amusing), but performance doesn't seem laggy at all so I have no idea what's up.
I'm also getting the message on my R9 270X, regardless of what driver I use. I've used various versions of Catalyst fglrx, Mesa 11.2, and Mesa 11.3-git.
No performance issues, but some games prevent me from choosing high texture settings, because they think I don't have enough VRAM.
An interest note, while the issue still persists in big picture the steam system information now shows the correct value:
Primary VRAM: 6144 MB
Perhaps copy/paste or share code? :-)
For kicks, much update software since original posting:
Distro: openSUSE Tumbleweed [20160913]
Kernel version: 4.7.3-1-default
OpenGL version string: 3.0 Mesa 12.0.2
OpenGL renderer string: Gallium 0.4 on AMD TAHITI (DRM 2.45.0 / 4.7.3-1-default, LLVM 3.8.0)
OpenGL core profile version string: 4.1 (Core Profile) Mesa 12.0.2
Xorg version : 7.6_1.18.4-1.2
xf86-video-ati version : 7.7.0-1.3
DRI3 enabled
Hardware: Radeon HD 7970 ghz
This issue should now be resolved.
First, in the kernel this was resolved in linux 3.17, and now in ~mesa git~ EDIT: mesa commit is a fix to scaling a GALLIUM_HUD graph and is unrelated. Waiting for confirmation in a point release of mesa before closing.
Note: This issue should be strictly cosmetic and general performance is not expected to significantly change.
Closing as this should work with mesa with any kernel 3.17 or newer, fglrx is deprecated, and there are no reports of an issue with amdgpu.
Assume this is ATI driver issue so I will cross-post in their forum, but the big picture mode doesn't seem to think I have much ram when the card has 6GB (7970 Ghz 6GB).
