Is there any version of Premiere Pro/Encoder that doesn't have issues with NVIDIA??

I had a 5070Ti and trying to export video kept crashing my machine, I now have a 4080 and although hasn't crashed yet, exports extremely slow when there is any rendering that needs to be done. When it manages to get past the renders the speed picks up. I've used the same .mogrt files since v25.0 and I've tried rolling back drivers and PP/AME, even got call outs from CC directly. Even  Can anybody tell me what's going on? Is there ever going to be a solution?
