Re: [CsMain] hardware T&L for sprites

[Toni <to...@4d...>]

Yes i'm working on things Anders, but my tests today are a bit disapointing,
compiling CS in release mode and testing my level, changing the sphere form
3500 faces to 30000, revealed that
there's something wrong in code, a bottleneck i have to find.
The sphere only rendered at 11-15 fps in a AMD1400 with a GF3. Even when the
number of lightmaps is excesive (probably 30000 lightmaps, one per triangle)
and possibly the texture swapping kills all performance. There is just one
texture but a lot of superlightmaps i think.
By the way i expected at least 30-50 fps with the 30000 faces sphere. Well,
i hope i'll can do it better in next attacks to Transform acceleration.
Greetings,

Toni
