My take on the Detonator 27.20 drivers.

For me its was nay to the 27.10's and 27.20's but your system could be different. Id try them out and see what happens.

I was just updating drivers, and I had posted a detonator driver problem here.

The 2311 drivers ran great in UT for the opengl, but in d3d my fps dropped to 20.

I re-installed the 2183's and now all is well in Moretyland again.

pre 23.11 i was gettign at least 90fps in d3d its about 85 now. opengl was throwing 40. 27.10s have improved my opengl upto 90fps, not tried d3d offline yet.
