I've been testing the new Ui release-cadidate for about 10 days. For my purposes this works without any major problems so far. I mostly test practical training, short races, and then watch it all in replay. Mostly in Spa. I noticed that the replay sometimes jerked a little! Not always, but sometimes very easy, because the replay doesn't run completely smoothly. FPS are enough 65-95 available! Opponent so 23-29. I didn't notice that in the previous Ui version. My system: 6700K, GTX 1070, 16MB Ram Just as a little information note.
