Hello,few days ago i build i new pc with the 13900k and a zotac 4090 aio,works great but i realise that the most fps killere of all is a program,FSLTL…really kill a god 50/55 to 20/25 with the fenix,(all on ultra+4k)but the poi t is that only in some situations the gpu(overclocked by me a little,not…

It is most likely that your system is heavily CPU bound in the scenario you mention, so the GPU is not running at 100% (because it doesn’t need to) and hence is down clocking with the lighter GPU load, regardless of your overclock settings. This is nothing to worry about and is normal.
