I don’t know the inner workings of FS, each update is a mystery and a lottery because nobody knows who may have a problem.
DX12 has not given me better results than DX11, not at least in what is visible on the screen and it is not a higher amount of FPS. I did not have any improvements with V-Sync either, quite the opposite in my case, and finally I do not need to use the FPS limiter because it does not go much more than 30 or 40 at the most (despite the fact that the AMD program mentions that FS2020 has a “marginal” performance with 52FPS when logging, 52 FPS that I have never seen in operation.
As I said, this has to do with a temperature problem, I don’t know if it was in the last update or the previous one since I hadn’t been using the Sim much and I didn’t look at the temperature either, I only paid attention to that when I felt excessive heat on the tempered glass side of the cabinet even though the coolers were running at high speed.
In short, in these last days that I was carrying out tests, I accumulated more than 17 hours of flight and the temperature is maintained. Undervolting and VRAM throttling have worked well for me.
