This holidays I spent time on online gaming with AMS2. The Wheel feel is really good in this game wiyh cloud tuning and I can keep a steady 120Hz with a I5-9700k \ GT1080Ti on a 2K resolution whitout any problem.
However I noticed lag a jerk on display during Online session only. I finally found it this the UDP broadcasting that cause this problem. Seems the broadcasted data give some headache to the game mixing with packet from online data server. I set UDP to OFF and kept the Sharemem to ON and problem dissapears which make sens as Sharemem doesnt flood your ethernet network
So far it is the only game I noticed such behavior.
if you see me online wave your hand.. my nickname is tofod_qc
hope this help someone
