for some reason a majority if not all games are limited to only 384MBs of video memory (VRAM) instead of it's full 2048MB dedicated memory. I read somewhere that disabling "Sych with VBlank" in the OpenGL menu would resolve this, but it did not. Now what could be the cause of this?

Take note that all 3D-applications tested have been run with Wine 1.5.26, PlayOnLinux 4.0.14 with AMD Catalyst 13.1, 13.2 and 13.3-beta3 will crash at random stating that there's not enough video memory or that an applications error has accord, which make my first impression of Ubuntu extremely unproductive, limited and most important unplayable.

System information:
Wine build: wine-1.5.26
Platform: i386 (WOW64)
Host system: Linux
Host version: 3.5.0-26-generic

Is there a solution to this problem? How do I make either Linux or my 3D-applications realize that there's more dedicated video memory available for my HD6970? Are there appropriate commands for this kind of issues, or are there other applications much like Wine/ PlayOnLinux that may utilize my applications and full memory better?

Ubuntu showing only 256mb of vram when it should be 1GB

Max VRAM supported by open source ATI radeon

Thanks in advance Raklödder

Steam Big Picture mode reports incorrect low RAM numbers. I believe this this a problem with OpenGL but OpenGL 4.5 fixes this, at least from what I've read. I'm not certain and don't take my word for it. Further research will show this is an extremely common problem. I'm looking into ways to force VRAM size myself just like you can with WINE, but in Linux and any programs that will still need forced VRAM numbers. It's not automatic for AMD users, neither open source nor FGLRX. – user319657 Aug 23 '14 at 6:41

How are you determining that the GPU only sees 384MB of VRAM?

It's likely that only programs run in Wine are seeing 384MB of VRAM. This would be because OpenGL doesn't (yet) provide any way of querying how much VRAM a card has, so Wine is forced to guess; it might be guessing badly for you.

To tell Wine how much VRAM your card actually has, you want to set the VideoMemorySize registry key. You can either do this following the steps on the UsefulRegistryKeys Wine Wiki page, or run the command winetricks videomemorysize=2048 at a terminal, which will set the registry key for you.
