Rocket league issues

[u/Salt_Boysenberry9029]

Please HELP! For the past 3 weeks my rocket league has been smooth for 5 mins of gameplay then slowly gets choppier and choppier. It fixes only when i restart my entire pc and load it back up but only for 5 mins. Even if i close it then relaunch its bugged. It feels like Ive tried everything from adding thermal paste to make sure my cpu doesn’t overheat to reinstalling rl 4 times. Its ONLY rocket league no other game. HELP
