--- Comment #6 from Roderick Colenbrander thunderbird2k@gmail.com 2010-04-30 04:18:38 --- This bug is quite different from bug 22478 which is about a performance regression. I'm not actually sure if 22478 is a valid bug or not. I looked at that bug with the reporter on IRC and he experiences a big drop due to a patch I added to 1.1.43. He is using a Geforce7 but I can't reproduce the drop on dx10-class GPUs like a radeon hd3450 and a Geforce GTS360. The patch fixed an actual bug and I guess this code (FBO stuff) is not efficient on older GPUs, so the issue might not be solvable and I'm keeping the bug as a place holder.
The issue described here is quite easy to fix (I posted a patch to wine-patches but it needs more work but can be used safely). It is about preventing unneeded gpu -> cpu -> gpu uploads which slow the game down a lot.
