Tropics 1.3 on R300g ( R520)

[Beiruty]

Tried to download and run tropics 1.3 on my R520 running latest r300g mesa.

Code from here: http://www.bestfreewaredownload.com/...-eheqkftx.html

Here is the crash:

I believe developers are working on this already :

https://bugs.freedesktop.org/show_bug.cgi?id=28294#c11

Thank you!

There is the "floating" branch that adds ARB_texture_float, ARB_half_float_pixel, and ARB_color_buffer_float to Mesa, but it's unmaintained currently.

http://cgit.freedesktop.org/mesa/mesa/log/?h=floating

Brian Paul's position on a potential branch merge is here:

Perhaps a stupid question, but would r300g hardware be able to take advantage of this if/when floating is merged?

[Beiruty]

as per bug thread, R520 do support this function.

Thanks! (And I even subscribe to that bug, guess I need to pay closer attention... )

Of course it will, it's almost implemented in master! The only missing things are the blend color and alpha-test. Other than that, it should work if you merge floating to master, but it has never been tested.
