Okay, I understand that ATI drivers suck, fine, but whenever I use shaders, I get a rather dramatic drop in geometry performance, I’d go from 75mtris/s down to 50mtris/s in a single textured, coloured example.
The problem is clearly not in shader complexity (the simplest shader possible slows down),
I’ve been experiencing this for about 2 years now, am I going insane?
Currently I’m using a 9600 pro, catalyst 6.4 drivers.
