Massive Input lag with arc raiders lsfg dual gpu
As the title says, I'm using lsfg and it seems no matter what settings I use the input lag is unbearable, it feels like the screen moves almost a full second behind my mouse.
I play 4k, all setting maxed, no frame gen on a RTX 3090 Kingpin, My fps usually sit in the high 50s but can go as low as 47 and as high as 70+ depending on map etc....
It plays great with my single 3090 kingpin with no fsr or lsfg but as soon as I try using lsfg with a RTX 2060 super it's completely unplayable, I've tried almost every setting I can think of in lsfg but the input lag still remains very high.
Specs:
Ryzen 9 5950x
3090 kingpin (2060 super secondary)
64gb ddr 3600 (4x 16GB)
Gigabyte aorus ultra x570 revision 1.0
Windows 10 pro
P.S. I have a GTX 1080 kingpin, would this be better than the 2060 super? Or would i lose newer technologies since it isn't an rtx card? If I did, what would I lose?
Note: I also tried lsfg with my 3090 and a 3060ti but I recently sold it, the input lag with the 3060ti as a second card also had massive input lag.
