Games dropping frames on gaming PC

[JMC47]

You can try asynchronous (skip drawing) to rule out shader generation altogether. It may result in some visual issues though. If it fixes the framedrops, then the issue is your graphics drivers stalling during shader generation. If it doesn't fix your issue and you're still dropping frames in Melee, you may want to consider looking for something else that would cause your computer to suddenly be occupied. Melee is super lightweight and shouldn't be bothering your computer at all.
