what were your FPS with the 256x256 textures?

There's still a lot of room for improvements (my CPU is almost at 100% all the time), but it's a good step in the right direction

(I'm on a dual monitor setup, so I'm not 100% sure that my NVidia uses 3D acceleration... I'll try this at home and see if the performances get better).

Could you please provide screenshots on multiple zoom levels?

I went from 11 FPS with 256x256 to ~20 FPS with 128x128.

The CPU use still seems to max out though, which is rather undesirable.

The MapWnd code needs to be essentially rewritten from the ground up using VBOs (vertex buffers that reside on the video card). Instead of using GG::StaticGraphics, the textures should all be rendered from a single buffer, one texture at a time (i.e. all instances of the first texture used, then all instances of the next, etc.).

The starlanes, fleet lines, etc., could similarly all be rendered using one function call each, if there were a buffer set up properly with all the vertices in it beforehand.

I'm going to work on this very soon.

Around 20 at normal zoom, 40 at max zoom in, 15 or lower at max zoom out (with a peak of 5fps).
