I had to see if Barefeats reports and benchmarks about improvements to Nvidia drivers was true. 50-60% improvement in just one incremental driver update didn't seem real. Maybe it is. Maybe it isn't. Maybe it was and it has disappeared. Maybe it's just for OpenCL and not OpenGL. Let's see. http://barefeats.com/gtx980ti.html I only have Tombraider and Metro Redux to test. Barefeats tested web driver 346.02.02f02 against 346.01. In Tombraider they reported the game jumped from 53fps to 84fps running on GTX980. But curiously the GTX680 and GTX980Ti are in the same ballpark when they shouldn't be. In the older driver the difference was clear to see. In the new driver they were much closer together. 346.02.02f02 has been updated since because it had a nasty bug causing Safari to crash. So I'm testing with 346.02.02f03. I tested Tombraider at 1920x1200 on the GTX980 installed in 12 core X5690, all highest settings (attached). If Barefeats was getting 84fps at 1440p I should beat that score at 1200p. In Yosemite the Tombraider benchmark scored 58.3fps. That is perfectly in line with the scores in 346.01 and much slower than the score of 346.02.02f02! That either means 346.02.02f03 has taken a step backwards OR 346.02.02f02 was just a fluke (higher numbers but reduced quality?). More testing is needed to find out what happened here. Furthermore I have tested El Capitan with the beta web driver 346.03.01b06. This is an even newer number. The Tombraider score was 57.3fps. Edit.
