I have gtx 1050 ti and AMD Athlon x4 750k Quad Core 3.2 GHz , 4GB ram , okay i know that i dont have the best cpu but on steam the mi nimum settings are AMD Phenom™ X3 8750 processor or better Video card must be 256 MB or more and should be a DirectX 9-compatible with support for Pixel Shader 3.0 .I have a way better pc to run this game, i tested a couple games , R6 Siege runs on 80 fps with everything on ultra , but CS:GO runs with 70 fps and theese 70 fps are dropping to like a 20 fps, I dont know what hapend i had the saim fps or more with AMD Radeon 7 700HD , but it started lagging and i bought a new one but it's still lagging i am thinking about buying a new cpu but this is unnapceptable still , My pc configs are way better than the minimum and i still cant run csgo on low setting 50 fps stabile or 60 it just goes from 70 to 10-30 on Dust2 , so i dont think that i need to talk about the other maps. Thanks for the help if u help and sorry for the bad english
