I am new to Zwift, maybe 3 weeks or so including the free week. It’s run just fine all this time, I ride every day, working on level 11, so it’s not like I haven’t used it much. The last two days the graphics stutter to distraction. Even at the map while selecting a ride it stutters while drawing the route!! The PC is a desktop, Core i5, 8GB Ram, Windows 10 Pro, Nvidia GTX 660 with 2 GB. The PC is dedicated to the trainer. Nothing has changed. I have rebooted, uninstalled Zwift and reinstalled, updated graphics driver. The PC is on wired gigabit Ethernet, so no network issue. Working Ant+ dongle. I have a first gen Kicker, all that, power, speed, cadence, hr, work fine, just the stuttering.
If an iPad or phone will run Zwift, how can I have problems with graphics on a desktop PC?
I saw the three or four old thread regarding this, but no real solution there.
OH, and the CPU is running 30-35% and the GPU ~50% when Zwift is running,
