So it looks like any of the Intel 945 chipsets (945G/945GM/... maybe 955 also) do not support NPOT textures and don't support ext_texture_rectangle.

My game can definitely run on this chipset and even get 60+ fps but I have to run my game in POT textures to make it fast. I want to be able to support NPOT to make it easier for the modding community to be able to mod my game. I could just make it a rule where they have to use POT textures.

Or I can do a texture atlas.

So my question is should i switch to texture atlas or switch to ext_text_rect or just keep to power of 2 textures.

And on these chipsets 2048x2048 is max texture size, so I would probably have to make 5-10 atlases...? possibly more.
