[Wine] VideoMemorySize registry key not being applied? [wine-1.1.2]

[bradl3yj]

I am using Ubuntu Hardy, using the latest release of wine from the wine repos. I have an nVidia 7600GT with 256MB of video memory. One windows game i installed, Medal of Honor Allied Assault, has a simple config utility that sets game settings based on your hardware. This utility is detecting only 64MB of video memory.

I tried setting it using wine regedit, HKCU>Software>Wine>Direct3d

Set a string value under that named "VideoMemorySize" and set it to 256, the MOHAA Config still reports 64MB. I tried setting it as a decimal DWORD value instead, same.

This could be a bug in the MOHAA config, but how do I know that other games are taking advantage of more than 64MB?
