Guild Wars 2

Does anyone know how to control the Cstats and force the GPU to be in a certain state?
I found a nice bug in the 13.9 and 13.12 drivers last night that when your CPU cant keep up the GPU will enter cState 0 (Max Power saving) until the CPU kicks in again.

This makes the GPU throttle at 50% of its highest possible utilization because its actually doing 100% 10% 100% 10% over and over again, until the CPU can spike back up to 80-82% Utilization (Example, Moving into LA where stuff is just slow, vs sitting in QD).

If I over clock to my 4.6Ghz then it doesn’t do it as often, If I roll back to 13.4 it doesn’t do it at all. It looks like AMD updated the power control DLLs in 13.9/13.12 for these new features and its screwing with performance. I think a work around would be to enforce cState 8 so that the Core wont get throttled down to 300 (from 1800).

Anyone have any ideas? Google searching has failed me on this search.

bump for good info and hopefully solution.

Bump. I think this may be the problem with why all of sudden FPS dropped to 1 when it used to play Great on high settings. I can’t even play the game anymore now because of it.

System Model: Dell Inspiron 7520
i5 2.60
6 gb ram
1gb dedicted video ram (AMD radeon HD 7730 M)
Yes, I made sure switchable graphics was enabled on this game.

Little update;

I put my HD7790 on 13.12 drivers. And immediately it will drop the Core down to 300Mhz (cState-0) and will not budge from that setting no matter the Stress on the GPU.

Installed MSI Afterburner, set the power slider to +4, and that releases the cStates Lock.

SO….Pulled my aging 650w PSU and put in a 780W, and put things back to defaults and it still worked. Cleared and Cleaned the Drivers, rebooted and tested with 13.4 13.9 and 13.12 are all working. Seems like it was a weakening PSU that was preventing the driver from pushing the higher cStates.

Seems like if the GPU cant pull a stable 38AMPS or so, it wont lock into higher cStats.
