nickspry: Game loads properly about 50% of the time, and gives me smooth 60+ FPS. The other 50% of the time it loads and alternates jerkilly between 2 and 9 FPS and is completely unplayable. Seems to be no pattern to when or why this happens, and I'm stumped. I'm using a new GPU which I thought might be faulty, but all other games play fine with healthy framerates. Any ideas appreciated.

Strix GTX 970
i5 2500k
8gb RAM

Jamie.monro: I don't know if I can help much, but are you using Nvidia inspector by any chance?

I have noticed one case recently where my GTX750 refused to run at full speed when starting TW3 and so had very low FPS.

I didn't think much of it at the time, but had to reboot the computer to get the GPU to engage at full speed when switching to a game.

Unfortunately, that doesn't probably help you much if you don't have Nvidia inspector; but I wondered if it might of been a small bug with the program version that I had.

If it runs poorly, does exiting the game and restarting it work, or do you need to reboot to get it to work at full speed again?

gunsynd: Some other processor might be kicking in and slowing down.I had one game that played
brillant then at a certain it went haywire,I thought it was the game but then realized it was
my anti-virus doing it's daily update.Check or record your processor usage and see if
anything kicks in when it play ups.

nickspry: Hi, I think I'm only running the Asus software that came with the card, but I guess that could be causing a problem too so I'll check it out.
Sometimes works after a restart, sometimes not. It's a very erratic problem.
Thanks for the suggestion.nickspry: Thanks, I'll give those a try.
