Does Wine use past the first 64MB on any video card?

Does Wine use past the first 64MB on any video card?
This question applies to all wine versions.

I have heard it stated before that wine only uses the first 64MB on your video card either in direct3d or opengl modes. Is this true?

If it is true is there a registry entry that can be added to make wine use past the first 64MB on your video card?

I apprecaite your help in this matter?

The 64MB limitation was a long time ago. Wine has been changed to try to detect your video card and guess how much memory it has.

In case it guesses wrong, here is the registry key:
HKEY_CURRENT_USER -> Software -> Wine -> Direct3D -> VideoMemorySize
See http://wiki.winehq.org/UsefulRegistryKeys

For example: if the card is a GeForce 7600GS, those usually have 256MB and that will be wine's guess. However some have 512MB, in those cases it may be necessary to set the registry key manually if you want Windows apps to see more than 256MB.

Along the same line as the Direct3D key can you add an opengl key as follows:
HKEY_CURRENT_USER -> Software -> Wine -> OpenGL -> VideoMemorySize

Thanks again

Along a similar line: Is there a way to easily detect the value Wine's
using for the memory size of your video card?

Also: I see from the docs that you set the value in MB, but do you need
to define it as a string, dword, or other? I would assume dword,
putting in the hex equivalent, but without knowing the answer to the
question above, it's impossible to test.

This question applies to all wine versions.

Wine does not use video memory directly - OpenGL API does not allow that. Wine just creates objects (for example textures) and it's up to OGL where they are allocated.
Wine just "simulates" amount of memory for windows apps that want to know how much there is and how much left.

No, you will have to enable d3d debug channel and grep for "GetAvailableTextureMem"

Also: I see from the docs that you set the value in MB, but do you need
to define it as a string, dword, or other?

Doh! Missed that in my hurry down to the appropriate key. Thanks!
