Too many unneeded updates = severe lag for every game mode

I hope my Autism won’t be a language barrier, but I’ve been experiencing extreme amount of lag regardless of which graphics setting a select (i.e, cinematic, very high, high, and so on). I have a budgeted high-end gaming pc that I built, and I never had any issues with any of my games via Steam, except for war thunder.
Now, I ain’t no dev… but the updates need to stop, its not a necessity. Advanced Shader Delivery (ASD) and DirectStorage technology is top priority.
