Pc to Pc streaming with Razer Ripsaw?

So I've got a fairly beefy Gaming pc that i used to stream on but have lately been using NDI with my laptop as my streaming device but the video quality isnt where I want it. It's still a bit hazy at times. I invested in the ripsaw but I cant seem to figure out how to get it to work with my Gaming pc and Streaming pc. I currently run a 1440p 144hz monitor with only display port and no DVI port i my graphics card and i have tried the OBS method where you preview screen onto the virtual monitor (being the ripsaw) but when i enter a game, it become VERY laggy. I've tried both display and game capture independantly but the gameplay is very laggy, except for games like Overwatch and OSU, but since i mainly play Apex and R6S on stream, it doesnt seem to work. Any help would be appreciated! P S. I use streamlabs OBS on my streaming laptop but regular OBS on my gaming PC.
