Check both Premiere and Media Encoder render times and performance compared to 14.3.2
Many users realised that render times both in Pemiere and Media encoder changed due to the new render system implemented in versions newer than 14.3.2.
In fact, this is the version in which everything works fine for me in render times. Even proxies render much slower than before (the format doesn't matter).
I have tried every new version (even 14.5) and the problem is not solved. I use Premiere for years and I have checked every file in my system, formated, and so on... and nothing!
It is not a hardware nor drivers issue. It is a new render system implemented by Premiere and Media Encoder (I guess it was implemented in 14.4). I asure you this issue is a software one because I use dual pc system and I had installed Premiere and Media Encoder in both Intel and AMD. Here I attach their specs:
PC1: Intel i9-9900k, 32gb RAM 3600Mhz DDR4, GTX 2080ti.
PC2: AMD 3950X, 32gb RAM 3600Mhz DDR4, GTX 2080 Super.
