Hello , I need help , my games became very laggy , idk why. I bought last year Prototype 2 and I played it yesterday , and it became incredibly laggy. Tomb Raider too! I bought a new MSI GTX 660 2GB GDDR5 , but they are still very laggy. Especially GTA4 , I know that GTA4 is badly coded for PC but it's still laggier than before , can someone help me? PS: My CPU is AMD Athlon II X2 250 3,0GHz ( Dual Core ) and I've got 2x2GB 1333 ram

I upgraded my PSU together with my GPU , becouse the old one wasn't enough powerful , the new is Corsair GS600
Here is a picture of the CPU and GPU usage while playing Tomb Raider in the shanty town ( biggest map ) It works there with 6-10 fps.http://s7.directupload.net/file/d/3487/dw2tg7hu_png.htm And yes , I could play all these games well before, I always had a tiny lag but now , some of my games became very laggy , especially Prototype 2
