CrossOver Support - Community Forums

Hello everyone,

I use Crossover since almost a week now and really love it. It installs mostly all of my progs and games very simple and without any complications.
However for some reason my graphics device having the latest propetary generated AMD Beta driver installed and being recougnized correctly in Ubuntu 14.04 and working fine so far with native applications. In crossover however it is being recougnized as a 2900XT resulting in not fully supporting the full 2GB of VideoMemory and also very likely not using most of the gfx cards cores. I have tried several games. Torchlight 2 runs ok, reduced but playable framerates. Hard Reset low stuttering framerate on low settings unplayable. Call of Duty 4 and Black Ops unplayable framerates no matter what setting. 7 days to die lagging framerate unplayable. Path of Exile Medium settings playable framerates.

I am very sure that a worked over gfx detection could fix the problem. But of course there might be other sulotions and I am very looging forward to read about them.

In advance thx for trying to help me out.

Hi,

The detection is unlikely to cause this issue. The video memory is managed by your OpenGL driver, which knows the correct amount. The number we report to the game only matters for some rare cases, like games that try to fill the entire video memory at startup. OpenGL does not have a proper way to query this information, so we are trying to guess it from the GL renderer string.

Fglrx doesn't have particularly good performance. It is hand-optimized for a few popular games / benchmarks like Unigine and the source engine, but otherwise it runs at around 40% of Windows performance in OpenGL applications (I tested that with UT2004, Lightsmark, Unigine Heaven and Xonotic). That said, it should run most games at playable speed. I have never tested Torchlight 2 or Seven Days to Die, but Call Of Duty 4 (aka Modern Warfare) should be playable on recent hardware. Please make sure that no other process is consuming CPU time. You can also play with your Window manager to see if desktop compositing causes problems. If you cannot find anything obvious I recommend to open a support ticket.

This is because this card is not currently entered on the Wine GPU table so we guess. However, with the card it defaults to, you should be getting a decent video memory size (512mb).

I have a few thoughts, if any of these make life better for you, then gathering some information from you and patching Wine may be possible (or you could try your hand at it!).

My first thought is that if you manually set some registry keys, the game may respond.

I would start with:

HKCU/Software/Wine/Direct3d/VideoMemorySize

I would set it to 1024 or 2048. I don't know that this will truly help, truthfully the video memory size should not affect game play though there are certainly instances where it does.

Then you might try setting the dword values of:

HKCU/Software/Wine/Direct3d/VideoPciDeviceID
HKCU/Software/Wine/Direct3d/VideoPciVendorID

You would need to get them from your device. Open a terminal and run:
lspci -n

Look for the line that is "0300: 1002:####"

"0300" should denote the GPU (video/graphics card), 1002 is the VendorID (assuming you are using AMD, it is 1002, if it's Nvidia it should be 10de) and then the last four characters are the device id (numbers and letters are acceptable). You can set this as your device or you can use an older device. Mine is the AMD 7970 and the device id is "679a", setting the id for the 7970 will be like setting the video memory size to 2048 and it may trigger a rendering path in the game (as in, the game may know the card without Wine's help).
