Setup good enough for 144hz/1080p?

I get 144fps with drops to 130 on low settings 140%render scale?

Do i just need to set the render scale down or is my setup to bad for stable 144fps?

Since this is an enthusiast-level question and not an actual problem that requires troubleshooting, your thread would be best served in the General forum.

drop everything on low except for textures, 100% scale.

my boy never use 140% render scale :d only scale % it should be 100% and maybe 75% for extra gians your pc should be able to run 144fps normally :d
