Re: Texture limits

Use a texture atlas for the font.

Also, a limit of 8 textures seems highly suspicious....

Re: Open Arena problems

That's strange, its looks like the only available resolution your system has is

Code: Select all

Available modes: '1360x768'
But the game is trying to request a resolution of

Code: Select all

...setting mode 3: 640 480
How do you have the pi hooked up, hdmi or analog video? If HDMI, what resolution is it using?

raspberry pi doesn't have neon instruction set.

it may be possible to use video core kernels to implement simd instructions.

definitely non trivial though!

Re: Quake 1 - how to run it?

I am pretty sure that quake1 contained a lot of hand written x86 assembler in order to get the performance it did. The x86 asm is not portable to ARM chips. The asm routines would have to be completely rewritten. Probably a non-trivial amount of work. Edit: maybe someone has built QuakeForge with Op...
