Hello!
First of all - very impressive software! Funny clip too, please feature more bass clarinet playing in the next one. I study Bb :)
I have at least one problem though, severe enough to make me stop using Zwei-Stein: on my computer the display is all blurry - it looks as if surface textures have very low resolution, then scaled up: this is true thorough all display space - text, graphics, controls, everything. I checked video card settings and didn't find anything that could enforce such behaviour. Other OpenGL apps work nicely too (even Blender, which is super-picky about OpenGL quality).
Also, I'm not sure if this is related, all operations are very very slow. At first I tried Zwei-Stein on my work computer and it felt exceptionally snappy. And when I got home it was such a disappointment. Both boxes are approximately equal.
Please advise, what can possibly be done to help this trouble. The computer is AMD 2600+ running at somewhere near stability threshold, 512M RAM, ATI Radeon 9600XT. I don't remember the exact version of the drivers, but this is the only version with which Blender works (iirc 3.39) and I won't ever reinstall them (just like I won't ever buy an ATI card again, but that's not the point)..
Thank you very much,
svo
