@nprofile1q... Ahh the good old 1650. It was somewhat of a solid gpu for the price, but sadly not really for blender, the 4 gb vram really pulled it back. I remember i had to do so many optimization to just fit on that damn vram.... good old time. And good luck with the new card..:blobheart:
@nprofile1q... For checking the animation in realtime you could use some simplify addon or just render a solid viewport animation which is pretty fast.
I can recommend Mustard's Simplify addon thats on the blender addon page. If i tick on everything except shapekeys i usually get the full fps in the viewport.
