MasterofNothing 10 Posted March 8, 2013 (edited) Hello everyone. I've noticed that sometimes, my GPU will scale to 2D clocks when I'm playing Arma 3. This is a pretty minor issue when playing singleplayer or multiplayer as a client (it might even be 'normal', even though it's baffling it goes to slower clocks while ingame), but when I'm hosting a server and playing on it myself, truly all hell breaks loose: GPU load / temperature: http://imageshack.us/f/202/80608313.png/ GPU speeds: http://imageshack.us/f/405/78591816.png/ CPU use: http://img801.imageshack.us/img801/9960/naamloosej.png And this is what the game starts to look like during these 'episodes' http://imageshack.us/f/600/2013030800003.jpg/ http://imageshack.us/photo/my-images/571/2013030800004.jpg/ Even with 0 players, the game starts running at ~5 fps (feels like 5 every 2 seconds), while it's completely playable when not hosting anything. Also, as seen above, the game starts looking like OPF. I didn't have this problem yesterday, until more than 15 players were on my server (then it started to become extremely choppy, while cpu load didn't increase, but I just figured my system wasn't fast enough). Now it's a guarantee. I'm running the latest (beta) drivers on the following machine: i7 920 @ 3,675ghz 6 GB DDR3 @ 1,75ghz AMD ATi 7870 XT JokerCard 2GB In any case, do you guys have some tips or ways to make sure my GPU runs constant clocks? Or would you, based on what I've posted, say that there is some other issue? Right now I can play the game fine as an MP client, but can't host and play at the same time.

Luckz 1 Posted March 8, 2013 My 670 seems to spend a ton of time at 2D clocks without looking like your screenshots. Share this post Link to post Share on other sites
kklownboy 43 Posted March 8, 2013 Google 7870 clock issue. Its a known problem. Share this post Link to post Share on other sites
dethica 2 Posted March 8, 2013 I have noticed my GPU going down to 2D clocks too. It happens when there is a lot going on - AI, explosions, smoke etc. Pressing ESC (going to the menu) restores the 3D clocks. Share this post Link to post Share on other sites
MasterofNothing 10 Posted March 8, 2013 (edited) Thanks for the comments. The only clocking issues I have in other games, or furmark, is that the core goes from 975mhz (boost) to 925mhz constantly, which doesn't make a lot of difference. For now, I've created a profile in CCC and am using it in MSI Afterburner. If anyone's interested, here's some info: http://www.overclock.net/t/626295/5970-fan-control-with-2d-3d-profiles-in-msi-afterburner Edit: After some thought, I reverted to the latest non-beta drivers, and now the problem seems to be gone somehow without the fix that I posted above. In BF3 the clock stays at 975 mhz, in furmark it's the same and in Arma 3 SP (haven't tried hosting a server yet, or MP) it's fine too. Edit: Hosting works fine too. Clocks are stable now. Seems it was a driver issue. I should mention that I did a complete sweep of the drivers before reverting to the non-beta drivers.
