Beta driver, BF4

Hey guys,

I am experiencing a problem while playing the bf4 beta. At first the performance of my gt650m was horrible...
After installing the beta driver from nvidia, things got better but it's still not as good as i wish.
When monitoring gpu usage, temperatures etc, i noticed a few things: Since installing the new beta driver, my gpu won't overclock anymore!
I used to +135 core clock and +500 memory clock, but in MSI afterburner it won't happen anymore. Also tried nvidia inspector, without succes.

The second problem i have, is the fact that the GPU won't boost anymore.

last driver, i clocked 970mhz (enough to run bf3 high/ultra @1080p)
new driver: default clock 745 (barely enough for bf4 beta low @720p)

The beta driver also affects the performance in other games

Am i the only one with this problem? Or could my gpu be broken?

Greetings from Holland,

Hello,

I don't seem to have the same problem. I am currently on the beta drivers from nvidia and can still overclock my gpu with msi afterburner. Though a slight overclock at GPU clock 845MHz and Memory at 1350MHz, I get somewhat playable frames at medium running at 768p. I hope you can find a solution to this problem.

Here is a video I recorded.
