Pretty sure that 2048 is a hard limit for maximum texture size for all=20
radeons up to and including r3xx/r4xx, IIRC all drivers for all OS=20
announce this value. So, no, there is absolutely no way you're going to=20
tweak that value, apps really need to take this limit into account and=20
work around it or they will not and are not going to work.
