Recently I upgraded my GPU from GTX660TI to GTX1660TI
and Rendering speed DROPPED extream!
On the 660Ti it was about 22-24 FPS while on the NEW 1660Ti it is 17 at best... some times less than 12FPS
Also Ver. 12 rendered FASTER than Ver. 16 (?!)
I am using the same settings and rendering profiles.
How could it be? what is wrong? How can I improve rendering speed?
