Here’s where I say Zwift really needs both a better means of selecting a default graphics setup - “APUs are stuck at Basic forever” is obsolete and this is also constantly breaking for new / weird cards. The PC client really should have better control over graphics options in general.
My main Zwift box uses a GTX970 - hardly state of the art - and I’ve tweaked the Ultra graphics profile for fancier looks, but basically editing an .ini file in 2021 is pretty dire. Even the Ultra profile leaves a lot of performance / quality room on the table. I’d argue even on this APU there’s room to go further at 1080p, or go up in render resolution.
