Hi, firstly my English is not good. So, I'll try to tell my problem with simlpy. I bought a grpaihc card from internet. Gigabyte RX 580 8GB (VGA RX580 8GB 256 BIT GDDR5 GAMING VGA / GV-RX580GAM-8GD-MI). When i start to play League of Legends or OverWatch, I'm geeting max +100FPS. How can i fix that problem? Because my old grpahic card was GTX 950 and It was better than RX580 about FPS.
