Here are some results from my Radeon test machine: . It's 
about a 1% increase in the real Windows apps, much less than I hoped for. I'll 
test on Nvidia tomorrow, and manually test a few more (newer) apps for which I 
don't have PTS tests yet.

For the curious, these are the URLs to my nightly trackers:
Radeon 5750:
Geforce 7600:

Watch out for the result ordering. Basically the results are ordered from 
newest to oldest(left to right), but the Radeon test is a bit more confusing. orders it in the order I uploaded the results. The Nvidia 
box boots automatically, the Radeon box is booted manually. So I forgot about 
the radeon box a few days and tested the older Wine versions a few days later. 
This is something Michael Larabel and I still have to work on.

Also the uptick in the Radeon tests is the test I ran with my performance 
patches applied. I forgot to change the result identifier, so picks it 
up like a normal nightly test.

Note that the Unigine Heaven tests are using the opengl backend right now. The 
other tests are D3D-based.

The source code for the d3d_clear, d3d_streamsrc and d3d_drawprim tests is 
available at (This is a git repo). I hope 
the server is stable finally.
