it will, i suggest you to use OBS Studio for recording, it doesnt drop fps and dont need a lot of space (2 hrs, 4-5gb) And to run gta san andreas on 120 fps you dont need a gpu like RedX mentioned, i have a low pc and i can run it on 300fps if i dont limit it, my specs: intel core i5-2400, 4gb ram, Gpu: AMD FirePro v4900
