Description

System Information
Win 7 64 bit
GF GTX470
6GB RAM
Intel Xeon w3520 @3ghz

Blender Version
Broken: 2.70 official build Hash: 19e627c
Worked: 2.69 official build

Switching to textured solid or GLSL with a 4k Texture will cause the framerate to drop massively to 0fps.

I started working on this scene in 2.69 and i dont had any issues with the framerate.

Download the file. I packed the used textures in the Blend, so watch out for the downloadsize.
If you have to: unpack the Textures
Just change in the "n" toolshelf the shading to "textured solid"
You will now see the textured ship, but in this situation i get around 0.2 FPS.
My graphiccard and cpu are around 25% usage when this happends, no intersting memoryspike or similiar to see. Maybe Blender is waiting for a thread to finish to draw the next frame?
Sadly this bug is pretty bad to work with, as i use atlastextures for my assets, so texturing without seeing the texture (because its to slow) doesnt work.

If you need more information on this issue, i will try to deliver as much as i can to solve this issue.

Tested on two Pcs (both intel cpus [i7 920/xeon w3520] and nvidia cards [gtx 470/ 460] latest drivers) happend on both of them.

This is likely because of cache limit being applied on the images. For now you can increase Memory Cache Limit in User Preferences ->System and i'll try to find a proper solution soon.
