Guild Wars 2

Just a note: flash, even with hardware acceleration off, will underclock your card to the low 500’s.

It’s a good idea to turn off anything which might cause flash to run.

I have flash video playing in background while playing GW2, my GPU clock speed isn’t underclocked.

If this work for some, awesome, doesn’t hurt to try. Seen this work around before, but I suspect the GPU underclocks when it’s not being worked hard enough due to a slow CPU not being able to keep up. Details in Q#4

If you’re running a 600 series Nvidia, you can use the new EVGA PrecisionX to lock the card in boost mode (EVGA calls it “K-boost”).

This can usually be controlled by changing the Flash player’s settings. If you turn OFF “Use Harware Acceleration” it won’t down-clock your GPU when playing videos.

It’s (usually) only when Flash uses hardware acceleration that it changes the GPU clock.

“Prefer max performance” in NVCPL might help too. Haven’t experienced this since my GTX260’s.
