I have the same problem as on this thread

https://forum.game-guru.com/thread/217903?page=2

It was running fine until today. I've recently upgraded to a GTX 1060 6GB but I've played one of the demo games on this card and it ran okay (although couldn't hold 60fps consistently) so not sure why it's suddenly running a new flat level at 2 fps. There are no other programmes running and task manager shows normal cpu, memory and hard drive use. Game Guru is installed on an SHDD hybrid drive. I've disabled avast, re-installed game guru but neither made any difference. The editor itself runs fine.

Any help is much appreciated.

Specs: Win 10 64bit, i5 3570, 8GB DDR 3 1600, Nvidia GTX 1060 6GB

Hi Matt

I have the same card as you and never had a problem, if I were you I would try unistalling Avast/AVG completely the AV that comes with windows 10 is quite good and has no overheads like Avast, also please run GG elevated (run as admin).

There seem to be many complaints about slow performance after exchanging the graphics card with a new model, most of them are due to driver installation without first removing the old driver's.
Another possibility is a bios setting on the mainboard for energy saving (power management should be set at performance).

Then there are the hardware settings, (start/control panel/hardware/Nvidia) (in win10 under all apps) make sure the 3D setting is set at advanced 3D.

Windows updates generally help, i find with hardware driver updates. But I use Windows 7 so im not sure if this is the same case with win10

Thanks for everyone's help but I found the problem, at least for me. It seems having Nvidia's Multi Frame Sampled AA (MFAA) enabled in the Nvidia control panel causes the problem. I've just turned it off and everything's working fine again.

Glad to hear you have it solved. Kudos for posting your fix as well, it may help others down the line

we need to wait for the new release of the program
