I talked about this before but i have learned a few things since. Here's what's going on .. i thought my video card was subpar till i used a different program which proved to confirm that my card is fine ,actually surprisingly fast. no matter what resolution i use my GPU doesn't want to perform when using VMS17 . However, when i switch to my Onboard graphics" intel UHD630" the rendering is much,much faster. i did go into the project settings and made sure Nvidia was selected when rendering . i talked to a 'puter shop today about what was going on and was told that my GTX970 should be much faster . it's a 4 gig card but is still very respectable for being 4-5 years old. i was all set to by a new one till i was told that. so that 's what is going on . i am open to any ideas. many thanks
Update : upgraded my video card to a GTX 1660super 6 gig and still is stop and go while rendering in 4K but it's faster than the onboard GPU by about 25%
