Hi All,

 

I just went from  1x 32´ 2K monitor and 1x 24´FHD monitor  to a  49'' ASUS XG49VQ resolution 3840x1080

and I started to see lags in Divsion 2 its like laggs bud FPS show still same value but its really anoying.

 

I have lates drivers for GPU

2080 Super

i7 9700k 3,6
32Gb RAM

 

Temperature is going to 83, and it looks like the GPU  MHZ is like jumping up and down.

Im sorry Im dont understand PC so well so Im asking for Help.

 

Thank you guys
