Here's my issue:
I play csgo on a 144hz monitor, it's connected to my gpu (RTX 2070) with a display cable. I get around 200-350 fps.
I tried connecting a 24 inch tv with hdmi to my computer to use as second monitor while streaming.
And for some reason when I have the tv connected, my fps in game seems low. When when I say that it "seems low" it's because it still says I have the same fps i always do, but it looks like 40 fps.
please help.
