The NVIDIA drivers 621.01 are causing lots of problems
, by Thibaut
The NVIDIA 621.01 driver released on October 21 is causing quite a stir. So far, several reports mention some very annoying bugs.
Among the reported issues are black screens, driver crashes, nvlddmkm Event ID 153 errors, stuttering with G-SYNC/VRR enabled in certain games, and mVolt+ voltage limit issues.
For now, it’s almost advisable not to download driver 621.01 and to stick with the previous version until a fix is released.
