Hello, I bought my xps 15 9570 a year ago (512gb ssd, 16ram, geforce gtx 1050 ti max-q, i7 8th gen) with the purpose of using it for university and also for gaming, in the beginning it was perfect, gaming fps as it should be. But in the last few months, the performance while gaming just dropped significantly. I play games like league of legends, hearthstone, cs go, and now valorant. They used to run above 100 fps with max settings, and now cs go and valorant stays around the 40fps mark, even if i turn down the quality setting, the fps still doesn't change, sometimes it hits 120 fps and then drops again. I updated all the system and GPU drivers, and also the BIOS, besides windows 10. Also tried to change some nvdia control panel settings to improve performance, nothing worked. Also tried changing the dell power manager to ultra performance, still doesn't improve at all. Overall the system performance is fine, but for some reason gaming used to be a lot smoother. I just don't know what to do anymore, and I am open to any advises.
