I've tested 305.53 drivers on the internal build and these seem to be from a different branch and working correctly.
I ran the
new patch 0.7.12.3212 on a fresh Windows 7/SP1 64 OS with the new Nvidia 305.53 drivers and only had about an hour to spend testing it but haven't seen any show stopper issues yet.
The most glaring bug is the one mentioned above where the propeller on the C172 turns black at certain angles to the sun.
I'm not sure what options in the graphics menu are actually working but I'm using 1920x1080 resolution, Vertical sync - full refresh, MSAA-8X, Shadowmap res - 8192x8192, Shadowmap samples - 16, Shadowmap kernel size - 4, Shadowmap distance - 20000, FOV angle - 100+ degrees, triple buffering enabled in the Nvidia control panel and the performance was almost completely fluid/smooth.
In the continuous log at the top of the screen I did get a red error message - “cannot find sRGB pixelformat for PF_RGT1”.
