Cool Viewer for ATi (Windows) with OpenGL fixes - some more testers needed!
Saturday, March 28, 2009 12:16:00 PM
You may have seen that I published a new version of the Cool Viewer that includes fixes for OpenGL - that's the system that renders your graphics - incorporating the patch and changes from VWR-12540. Thanks a lot to Luricos for providing these.
After some initial issues I think this viewer is pretty usable now and it pushes graphics performance up reportedly by 40...100% compared to the normal viewer.
Some benchmarks with this one on different hardware:
Intel Core 2 U7700, 1.33 GHz, Intel 945GM, OpenGL 1.4, 14.5 FPS
Intel Pentium M 1.86GHz, Intel 915GM, OpenGL 1.4, 23.6 FPS
AMD Athlon XP 1700+, 1.94GHz, Radeon 8500, OpenGL 1.3.1072, 31.5 FPS
AMD Athlon 64 3200+, 2.1 GHz, Nvidia 8600GT, OpenGL 2.1.2, 70.0 FPS
Intel Core 2 T7500, 2.2GHz, Nvidia FX570m, OpenGL 2.1.2, 93.5 FPS
AMD Phenom II 720 #4, 3.4, Nvidia GTX 260, OpenGL 3.0.0 160.0 FPS
Dynamic test results (60s train ride in Koh Kut, measured with fraps):
R3: Standard Viewer, R3c OpenGL fix, SSE2, R3e, OpenGL fix, SSE, Shadow just for comparison)
ATi (HD4830, 1400x900, Thanks TrasheVyper!)
R3) 1785 Frames, 19 min, 44 max, 29.750 Avg
R3c) 2178 Frames, 25 min, 46 max, 36.300 Avg
R3e) 2224 Frames, 21 min, 54 max, 37.067 Avg
SL 1.22) 1554 Frames, 12 min, 39 max, 25.900 Avg
Nvidia (GTX260, 1680x1050):
R3) 3924 Frames, 42 min, 86 max, 65.400 Avg
R3c) 4617 Frames, 64 min, 91 max, 76.950 Avg
R3e) 4463 Frames, 63 min, 89 max, 74.383 Avg
Shadow) 2615 Frames, 36 min, 53 max, 43.583 Avg
SL 1.22) 3436 Frames, 42 min, 85 max, 57.267 Avg
This means there is a measurable performance gain of about 25% for both, ATi and Nvidia cards. And compared to the official SecondLife 188.8.131.52 viewer it is 35% faster. Reported results in crowded places are even higher (40...100%, but that's impossible to reproduce with always changing traffic).
I'd ask all of you out there running on ATi graphics cards to give this a try and please report your findings back. Nothing to lose, only to win. You can install it in a different directory in parallel to your normal viewer.
Please see the details here, and also please leave your comments there. The version to try is 184.108.40.206 R3e.
