Marvel Rivals is dropping to 15 FPS during team fights on my ADATA 4GB DDR4 2666. This is unplayable!

The frame rate would suddenly tank to 15 FPS, turning the game into a literal slideshow, which was absolutely ridiculous. Trying to run a modern competitive game on 4GB of ADATA ValueRam is basically a survival challenge; the system was hitting 95-98% utilization and swapping data like crazy, causing severe micro-stutters. I tried turning on Windows Game Mode, but the memory was still in the red zone, which was almost funny in how useless it was. I ended up using a process manager to kill every single unnecessary background service and set the game priority to 'Realtime', while locking the page file at 16GB. AIDA64 showed read latency dropping from 110ns to 88-92ns, making the team fights way more bearable. I did accidentally kill my audio driver during the cleanup, which left me playing in silence for a bit, but a quick restart of the service fixed it. Temps stayed around 40-45℃. I exported the logs and saw the fan speed holding steady at 1400-1600RPM just to keep it alive.
