Hi Janne, so a 10,000 x 10,000 image is going to require a 381MB texture which is very large in size, also the texture has to be all in one single block of memory. That will probably have difficulty working on a card with 512MB or less of video memory.

Also a lot of video cards are more tuned towards game mechanics and video games do not use such very huge textures so they may have some particular limit built into the card.

Maybe try bumping up that MaxTextureSize value in moi.ini in a couple of steps, like try doubling it to 4096, and if that works ok on your card you can try doubling it again to 8192.
