Solution when GPU Is Slow

If your GPU is lagging, the first stop on the road to redemption is a driver update. Both Nvidia and AMD are engaged in a drivers arms race, with each company updating its drivers with an OCD-like frequency that’s impressive. And always check to see if there’s a new driver before you launch a brand-new game. You can find your driver version easily in both Catalyst Control Center under Information/Software, and in the Nvidia Control Panel.
Overheating can also cause the GPU to throttle its clock speeds, so monitor your temps using the software provided by your GPU manufacturer.
