I have a ok pc, not the best though. It has a GTX 1060 6gb gpu and a i5 8400 cpu. Lately it has had problems with severel games such as Battelfront 2, Warzone and even pretty old games lik CSGO. Most of these games ran smoothely a month a go, but now they lag. I dont think it has anything to do with my internet connection because i have tried it at a friends house (with fibernet) and it lagged there too. Please help. Thank you in advance.
