Made an account to post this. Have a SteelSeries Rival 300, mouse lag makes game unplayable. Move the mouse and have to wait 3 seconds for it to register even though everything else on screen is buttery smooth. None of the above suggestions have fixed the problem. This is honestly a shame because I was interested in checking this game out to see if I was interested in purchasing it. Now I guess I'll never know since I'm not spending $60 on a maybe. Congrats on the lost sale.
