Not realy, the combined average FPS for 347.09 is 81,18625 FPS, and for 358.87 its 89,09375 FPS. So basically +-1FPS per test which is really neglectable.
these drivers has finally fixed the stutter on windows 10 gaming!!! OMG im so happy right now! Measured the frametimes with msi afterburner in 3 games that were heavily affected by high frametimes and these drivers are getting a constant frametime with no spikes as before. very good news for us who were having stuttering on windows 10.
Ahh I missed that, sorry. I've been sticking with 347.09 beta for CS:GO since it performs the best, and it seems to be the most popular one as well besides 347.25 & 344.11
