I upgraded my PC to include a ryzen 7 7800x3d, 16GB of DDR5 RAM, an AMD 6950 XT saphire nitro + OC graphics card, 2TB SSD. when i start the game it will run completely fine. After about 20 minutes to a half hour it starts lagging so bad and the audio skips etc. i have to restart the game in order to play for another 20-30 mins and repeat the process endlessly. PLEASE HELP
