16GB DDR4 RAM (no xmp profile, because it caused bsods and I didnt want to risk updating the bios, it works fine without it, ~2666mhz)
NVIDIA RTX 4070 (Palit JetStream 12GB)
if more info needed (im sure it will be), i will send it;

Hi, so for the time since I got this card, I have recorded in 1080p 240fps just fine (it wasn't exactly smooth how I wanted it to be, but that was acceptable because I still have an old ryzen CPU). Recently, I tried to tweak my OBS settings, to maybe make it more smooth/make the files smaller (the cqp recording setting resulted in a very clear image, but files were very large). So I asked one person for their settings (because the rendered videos were very, very smooth and the only thing that was used was smart resample in vegas). Their gpu was an rtx 3060ti (so a lower model both in generation and hierarchy), capable even of 480fps recordings. I tried to copy the settings, but it wasn't 100% possible because of differences in gui (that was caused because of a different generation of the gpu). So I didn't succeed, I tried different settings on my own, and got these results (480fps, mkv): AV1: slideshow, low quality, vegas 18 pro edit can't import it; H.264: even worse slideshow, okay quality (like slightly compressed screenshots), vegas renders it and it looks exactly like the source video (a few screenshots). SMPlayer tells me it is indeed 480fps, but i think that's just a string, not a real value of fps.

I understand that:
1. The support won't be given if I record above 60 or 120 fps (I just want to find other people with 4xxx and 3xxx series gpu's to compare, and maybe find a solution);
2. It may be a hardware limitation.

It would be nice if we would be able to create a spreadsheet containing information about high fps recording on various gpu's.

If it's needed, I can send logs from OBS and possibly other things. I just need information how to do it. Thanks for reading :)

It's worth mentioning that after rendering 240fps - the video from 3060ti was way smoother (the cpu was ryzen 7 3700x - so better than mine)
