hi

GTX 970 here, I can go 120 fps on most tables using modified Engine.ini settings. You might need something a bit more powerful than that.

A 1080 or 1080Ti would probably work wonders with your setup, but that entirely depends on your processor + motherboard you're using for your cabinet. My i7-6700k probably can't handle RTX cards using the highest settings.

Thank you.
What settings do I need to change in this engine.ini file?

[SystemSettings]
r.SSR.Quality=3
r.SSR.MaxRoughness=0.4
r.Tonemapper.Sharpen=0
r.ShadowQuality=3
r.Shadow.MaxResolution=1024
r.Shadow.MinResolution=32
r.AmbientOcclusion.Method=0
r.AmbientOcclusion.Compute=0
r.AmbientOcclusionLevels=1
r.AmbientOcclusionMaxQuality=100
r.TemporalAA.Quality=2
r.TemporalAA.Upsampling=1
r.TemporalAAUpsampleFiltered=1
r.TemporalAACatmullRom=0
r.TemporalAA.R11G11B10History=1
r.TemporalAAPauseCorrect=0
r.TemporalAA.HistoryScreenPercentage=100
r.TemporalAASamples=2
r.TemporalAAFilterSize=0.09
r.TemporalAA.Upscaler=1
r.TemporalAACurrentFrameWeight=0.6
r.Upscale.Quality=5
r.Upscale.Softness=0

Here's what I use. I'm not sure if it'll help with your build specifically, but it's worth a shot. You can just paste this underneath the [CoreSettings] portion of Engine.ini.

Thank you kind sir. I'll give it a whirl.
