I didn't know what screen tearing was until 6 months ago when TADS explained it to me. I can safely say I've never noticed it occurring in any game I've ever played... genuinely.
I'm a fan of the Earth Defence Force series. So I definitely know what framerate drops are. I'd rather not have them, but they don't bother me.
Texture pop-in does bother me a bit, but again, I can live with it.
