i don't want spot shadows, but if the setting isn't low, the shadows of characters are flickering squares? is this normal in crossover?

imac 2.4 core 2 duo, radeon 2600 HD

Yes, this is a known problem. It is a limitation of the way offscreen rendering works. You can improve the situation by setting a higher screen resolution.

<technical>
A way to fix the root of the issue is to set the following registry key:
HKEY_CURRENT_USER/Software/Wine/Direct3D/OffscreenRenderingMode = "fbo"

This enables frame buffer objects for offscreen rendering. This doesn't suffer from the limitations of our default mode to use auxiliary buffers, but it has some bugs in Crossover, and it often triggers bugs in the drivers, so we decided to keep it disabled by default.

The problem is that the shadows are rendered to a 2048x2048 offscreen texture. The auxiliary buffer's size is the screen resolution. Due to that offscreen textures are limited to the size of the screen. The parts that are outside are set to black, white or garbage depending on the driver. Due to that the shadows are either missing, black quads, or flickering.

thanks for the reply.

i can put up with some bugs, but does it affect performance?

also, mac os x 10.5.2 will be released by apple soon.

you think it'll have some graphics related fixes? (for e.g the bugs hindering dx 90/95 progress)

10.5.2 has some bugfixes for games, we are aware of one fix we need for Guild Wars on the radeon HD cards. I hope that we see some progress on shader support as well, but I do not have high hopes. This problem has been around since years and was never fixed, so I doubt it will be fixed with a minor version number increment. On the bright side, the major obstacles affect the radeon X1600 and X1900 cards only, so dxlevel 90 may be possible on other cards in forseeable time.

thanks stefan.

also heard that current mac os drivers for the radeon hd 2600 cards are still terrible (worse performance than previous intel imacs (white)), and that apple/ati are working on improving them.

is this true?

and probably won't be part of 10.5.2, correct?
