Plutonium

xYzGalaxy it shouldnt be my pc because i looked at the minimum requirements for plutonium and my specs exceed them by a decent margin. Not to mention the base games work fine but plutonium doesn't even though it doesnt change the graphics or any graphic related features.

I installed Plutonium 3 hours ago but when i launched it and downloaded bo1 and booted to menu, i was immediately hit with hard lag and i was only on the menu?! I tried to load up a game and when i got in it was already down to 5 fps!? I played campaign and i get solid 60+ fps but when i use plutonium it just dips. I have more than capable specs:
CPU: Intel Core i5-1035G1
GPU (integrated): Intel UHD Graphics 620
RAM: 8GB DDR4 Single-Channel
It doesn't make sense that it should lag like this, I tried downloading bo2 and it did the same thing, the same with WaW. I had all these games in the past on steam and it worked perfectly fine but i lost my steam account. I have tried all methods I could find like disabling full-screen optimization, lowering graphics, etc. I did everything on this page and more. I want to enjoy these classics again. Help would be appreciated
