The good news is i just got my new card which runs better and faster than my previous, 3090. On my iray benchmark with the latest driver 5090 runs 50% faster and a lot more silent.
The bad news, daz studio, the software I mostly use to make all the renders does not support the 50 series gpus yet so i have to wait for on update first for the iray driver.
I did try to use the iray server with the latest iray driver but somehow Daz "tells" the server to try to render the scene with the old driver which does not support the latest gpus.
No luck there.. until there I still to use my old gpu, the 3090, and sit back, relax and wait for an update from Daz Studio.
