I did some benchmarks going from my previous driver version to this newest one, and they look promising so far!
Each was done with a sequence of 5 identical timedemo tests in TF2, before and after driver installation. Old driver was uninstalled along with all Nvidia components with a clean wipe using DDU. First run is tossed out and the average of the remaining 4 runs is listed.
-Previous driver (368.81):
139.34 fps ( 7.18 ms/f) 22.321 fps variability
-New driver (372.70):
154.19 fps ( 6.49 ms/f) 20.284 fps variability
*Note: previous installation had Nvidia 3dvision drivers, HDMI Audio drivers, and geforce experience installed as well, new install has only display driver and physX installed. I'm installing the beta version of geforce experience now and will test after install and report back if that lowers performance at all (doing testing with shadowplay off, but will bench the performance hit with it on too)
EDIT:
Results with GeForce Experience Beta 3.0.4.35:
-Geforce experience installed (program running in background, sharing overlay disabled):
156.10 fps ( 6.41 ms/f) 20.544 fps variability
-With sharing overlay enabled, but nothing activated in overlay:
157.12 fps ( 6.36 ms/f) 19.137 fps variability
-With shadowplay enabled in sharing overlay:
154.80 fps ( 6.46 ms/f) 20.225 fps variability
-With Twitch streaming enabled (720p 30fps 2.5mbps) in sharing overlay:
154.36 fps ( 6.48 ms/f) 20.112 fps variability
**Tested with an i7 4790k @ 4.7ghz, 980ti OC, 16gb DDR3-2133 ram & Windows 7 64-bit. System was restarted after driver install, and after installing Geforce Experience Beta.
Anyone else have similar results with this new driver? Do a bench before and after you switch and post your results here.
