[2021] [Performance]Sudden FPS drops after Update and Maintenance

Before this season I used to be able to play on 80-120 fps on what isn't the greatest. This new update seems dropped the performance to 20-60 fps in-game and longer loading times in the opening screens and operator selection screen. My graphic drivers are up to date and I have turned off match replay as advised by another fix.

Has anyone else been experiencing this and do you guys have any fixes in mind? Thanks in advance

My spec is : Dell G3 15 Intel Core i7-8750H + GeForce GTX1050Ti + 7.86GB RAM.
