As you already saw: Aiimag.es already applies full_precision for those graphic cards, but there's a bug in the backend that doesn't make it work (yet). :(
Apparently the 1650 models might not work at all. :(
The fix that makes the 1650 models work needs more VRAM than the 1650 model has. I'll keep you updated if the backend devs find a way to still make it work! <3
Can you open the options - > open settings folder button - > send me the player file on Discord (Sunija#6598)? v1.1.2 should work on your GPU, so maybe there's another issue. :3
