Newly installed drivers make rust worse

I recently installed a newly updated driver from geforce and it actually made my rust frame rates drop down dramatically. The driver is the Geforce R331 game ready driver. right after i installed it it made my game practically impossible to play. i use to be able to play on the make game quality setting but now even if i set it on fastest it still have crazy low frames. can someone help me please.

Contact the Nvidia support and check your driver settings first.

Make sure your settings in Nvidia control panel are ok. Ive tried the 331.82 driver and just updated to the beta 331.93 and no difference in frames

Also make sure your power settings are on maximum performance, not on balanced. This might be a laptop only feature but I don’t know what your playing on
