Best ways to squeeze every FPS out of WWE 2K26? (Visuals don't matter)

Hey everyone, Im trying to get WWE 2K26 running as smoothly as possible. Honestly, I don't care if the game looks like a PS2 title I just want a consistent framerate and zero input lag for online play and CAW-heavy matches. Does anyone have a guide or tips for maximum optimization?

• Config/Ini tweaks: Any hidden settings in the game files to disable heavy effects like shadows, crowd density, or reflections?
• Performance mods: Are there any "potato mode" mods or custom shaders yet?
• Background fixes: Best Nvidia/AMD control panel settings specifically for this engine?
• Window vs. Fullscreen: Which one is more stable for this year's release?

If you have any "secret" tips to boost performance on low-end hardware or just to eliminate stuttering, please let me know. Thanks in advance!
