I could run up to ~6 different windows in separate Qt widgets on
RedHat and a fairly large (texture-wise) scene without a big drop in
performance. Adding more windows decreased performance of course but
not at the rate you mention. Don't know if it makes a difference but
all windows were sharing GLContexts. The card was a GeForce FX 5700LE
nv36.
