Hi I have such a problem. I have this notebook (http://notebooky.heureka.cz/hp-probook-4540s-h5j83ea/specifikace/), just with the difference that I have Win7. The point is that every time I turn on Gta 5, the game only starts in processes and always consumes 25% of the processor. I tried to switch to the integrated graphics card (intel (r) hd graphics 4000) and run only from it, but only the first start screen with those shots will load and then it's just dark. Does anyone know how to solve this problem. Thanks
