Default Re: contention among multiple cards (poor texture-loading performance)?

Did you try running the program with multiple windows?

As mentioned in the original post, the "-many" (a) and non-"-many" (b) options ran at nearly
the same speed if there was only a single window. But if there are two windows -- even if they
are on different PCIe graphics cards and different X screens -- there's a big performance loss
with -many but little loss when just re-using one texture tile per window.
