Hi,

I recently build a new PC with i7 4790K, 16gb 2400 Mhz of Ram, 650W PSU and Gigabyte Windforce GF770 all on Gigabyte Z97 Gaming-5. I'm running Windows 8.1 pro x64 with newest 344.11 NV drivers, dual Monitor 2560x1440 & 1680x1050. The questions is - what can possibly be responsible that most of the time I have around 150 fps on Extreme (2560x1440) settings in Heroes of The Storm and other time I'm bearly getting over 55FPS on the same settings. Same issue applies to other titles like BF3, Crysis 3. Most of the time couple restars or flushing NV drivers fixes it, but still I have no idea what's causing the issue. I'll also give You a DxDiag http://www.iwokolasinski.com/DxDiag.txt

I have no idea what heroes of the stom is. What frames are you getting on bf4 and what settings are you playing? I just upgraded from that exact card so I know it pretty well.

Have you monitored your GPU and CPU temps while playing ? If not do it and report back

Heroes of the Storm is a DOTA from Blizzard. On BF3 on max settings and full screen resolution I normally get 60-70 fps and stable. But while under this "bug" around 10-15 fps. Diablo 3 for exp around 120-190 fps on FullHD, under a "bug" 30 FPS tops. Temps on GPU and CPU stay below 40c when idle, below 70c when games running/rendering. This issue is not happening during gameplay - it start right after I launch a DirectX based programme, and carries on until restart/reinstallig drivers.

I just noticed that it also appears on Windows itself when I launch the tile view the animations are jagged.

Turning off and on video card in Device Manager helps. So it must be driver related?

If you don't already have this, download it. After installing, open it. It will automatically scan your current driver and list the latest driver for you to update to.

Also, download http://www.techpowerup.com/gpuz/
Screenshot both the "graphics card" tab and "sensor" tab and report back here. Also let me know if you driver was out of date.

Seems a bit obvious :/

Your card shouldn't be idling at that clock, it should lower it's clock when idle. Go to your nvidia control panel, Manage 3D setting, under global settings set the Performance management mode to Adaptive. If it's already on adaptive then there's something running that is using your card, which may cause your sudden fps drop

This idle state was taken after a restart. GPU from the beginning was set to adaptive mode.

When you start getting fps drops etc, I want you to exit the game and screenshot the results of GPU-Z again to see if your gpu is under load.

I had to reinstall windows after some heavy security breach, firewall went down and so on. Problem with the GPU seems to gone away. GPUZ show normal card behavour lowering Core Clock, keeping power lever at apropriate levels. Probably something was wrong on OS itself. So big thanks for interest in this topic! :)
