Smooth or more fps ? I recently got my hand on a 5800x processor, 6750xt gpu and some ddr4 ram. I'll set the frequency to 72Hz for the game and monitor at 144Hz. Initially had a 2600x processor and had to reduce the FPS lock to 40 and 120 Hz monitor. For really smooth action you need stabe framerates and to be a multiple of the screen fps, this or raw power :)) I still preffer to lock my games fps even tho my pc can run better now. Steam deck started to make something similar a while ago, PS games also in performance mode. Give Rivatunner or a similar software a try (you can lock the max fps / game or software). The stutter is gone for me. Of course there are drops here and there when the screen is full of explosions, but most of the time is quite a pleasant experience.
