I am waiting for the parts of my build, and i have to use my old laptop. It has an i3-3217U with integrated HD 4000 graphics. I got a cinebench score of 67. I expected better, so i fired up csgo. I remembered, that i could run it 60 fps on low no problem. I struggled to get 40 with offline bots, and online was unplayable. I changed thermal paste, because i noticed my cpu runs on 90C at 100%. It got down a little, but no help. Cleaned my SSD, nothing. What could cause this?
