Sfera: a game with real-time path tracing rendering

Video looks good, but downloaded the windows executable (1.0devel) and nothing is shown on my HD5770 (juniper). Catalyst 11.12, SLG2 works just fine.

CPU support seems good anyways

You shouldn't have problem to run Sfera both from software point of view (i.e. updated drivers) both from the hardware (i.e. a 5770 is more than enough to run Sfera).

Can you post the console output ? Do you get just a black screen from the start ? No titles ?

Do you have multiple screens attached to your card ?

First, sorry, i got a 5750, not 70... Saphire Radeon 5750, 1Gb Vram, Windows 7 x64, 3 Gb RAM. Catalyst 11.12. Everything updated. (For reference, SLG didn''t work on this card between catalyst 11.7 and 11.11, but 11.12 worked again.)

Can you post the console output ?

Sure, the console output, running the RUN_SFERA_HIGH_CFG.bat:

Do you get just a black screen from the start ? No titles ?

Titles yes, just the reaytraced parts are always black.

: Black output

Do you have multiple screens attached to your card ?

No. Just one.

If you need another info, just ask. Thank you.

The problem may be here: you may have not enough constant memory on your GPU to run the HIGH_CFG.

Have you tried the default configuration (RUN_SFERA.bat) ?

Same black screen, nothing different.

Everything seems working ok, but no raytracing working. Maybe ATI did something to their drivers again?

I can just imagine how is that going to look in my nVidia SLI GTX590(4000+ CUDA cores) With 2 8core Xeons and 256GB of RAM.
Oh, wait, that's my dream machine :lol:

Compliments!
It looks awesome, a good proof of concept!
