> Here you are: 1.5.2 is the working case, 1.5.3 is the non-working one.
As you can see from comparing the log files:
* It's not the same version of the driver: E.g. only the 1.5.3 log contains the lines about Max desktop size vs. the Virtual directive. The driver from the working case may reserve a smaller maximum desktop size by default, leaving more video RAM for textures. If you don't need the additional space for resizing or rotating the virtual screen resolution, use the Virtual directive to limit the maximum desktop size.
* 1.5.2 uses XAA whereas 1.5.3 uses EXA. This can again have an impact on the amount of video RAM available for textures.
The net result is
(II) RADEON(0): Will use 8704 kb for textures at offset 0x1770000
in the working case but only
(II) RADEON(0): Will use 960 kb for textures at offset 0x01e08000
in the non-working case.
