hello,

is your texture data buffer a direct nio buffer or is it allocated on heap?

i recommend using Buffers.newFooBuffer() for buffer allocation whenever possible, since you are dealing with large buffers you may want to increase perm gen in case it wouldn't fit if direct allocated (-XX:MaxPermSize=)

if you already using direct nio buffers... please report back.

best regards,

michael

Just was trying to glTexImage2D 2 4097x4097 textures. The first one was
uploaded to GPU successfully, but the 2nd one throws above exception. This
means I can never have 2 textures of that size on GPU. Moreover, somehow
8193x8193 - is loaded to GPU without any problems - but it's size is 2 times
more than 2 textures of 4097x4097 are. This proves that I have enough memory
(but I think we don't really need to prove it with Radeon HD 5870? :)).

Guys you really have to fix it, I can't work like that :)
