make sure the mb bios is updated to rule out a bios bug. make sure the mb chipset and other drivers are up to date.
see if your anti virus has a gaming mode. may be it causing the error. if your running windows 10 make sure you have the newest direct x installed. make sure your gpu supports newer direct x 11/12. use msconfig turn off stuff you dont need running in the back ground. depending on the age of the game it may not like to be tabbed out.
-GTX 950 supports dx12
- space engineers is early access
Thanks for your help, I'll try the rest.
