Is this program ok? lossless scaling

I found review about lossless scaling on youtube. and I downloaded from steam. it works to me. it helped me over 20+ fps on epic bg first battle.(Im using rx570, normally 50~60 fps fhd on bg, arena, 5 dungeon) so I have a question. can I use this program while playing wow?

Yes you should have no issues.

However asking CS support could help answer it from a Blue team POV!
