so i was playing fornite and when i first launched it, it was at 250 fps, then after a match 240 fps, then after another match, 220 FPS. 220fps is the lowest it'll go.
here are my PC Specs
Intel Core i5 7400
GTX 1050 2GB (PNY)
8GB DDR4
Stock PSU That came with the Prebuilt PC.
i re-installed my GPU drivers and fortnite isn't the only game that this happens on.
rocket league, CS:GO.
could it be because the stock PSU hasn't been replaced yet? it came with the PC i bought.
i think the stock PSU that is currently in my pc is 290-300w and the 1050 requires like 330w.
