Chute de FPS (En jouant 1/2 heures) problème de config où autre chose ?

Bonjour,

J'ai un soucis avec mon pc

Quand je joue un jeu tout fonctionne correctement mais 1/2 heures de gameplay chute de FPS 20/30 aucune raison

J'avais ajouté des rams et changer ma carte graphique 960 au 1660

Nvidia à Jour
Nettoyage du pc zéro poussière
CCleaner
Réinitialiser mon PC
