surf8.s asm - taking out the lightmap smoothing

[mankrip]

[leileilol]

More results, this time with memory waitstates to 0 (woo bios tweaks), timedemo demo2

Viewsize 100 (default):
No lightmap smoothing: 13.8fps avg
Lightmap smoothing: 13.6fps avg

Smallest viewsize:
No lightmap smoothing: 22.6fps avg
Lightmap smoothing: 22.5fps avg

The mip bias differs in a smaller viewsize I think, so the difference isn't as large.

EDIT: -nosound results:
Viewsize 100 (default):
No lightmap smoothing: 14.5fps avg
Lightmap smoothing: 14.3fps avg

Smallest viewsize:
No lightmap smoothing: 24.2fps avg
Lightmap smoothing: 24.2fps avg (WTF!?)


For what it's worth, here's an Engoo dos build benchmark run, also -nosound (since sound's C this time)...

Viewsize 100 (default):
No lightmap smoothing: 11.4fps avg
Lightmap smoothing: 11.3fps avg

Smallest viewsize:
No lightmap smoothing: 22.2fps avg
Lightmap smoothing: 22.1fps avg

Viewsize 100, r_lowdetail 1:
No lightmap smoothing: 14.7fps avg
Lightmap smoothing: 14.6fps avg

Viewsize 100, r_lowdetail 1, d_mipscale 6:
No lightmap smoothing: 15.1fps avg
Lightmap smoothing: 15.1fps avg

Viewsize 100, r_shadowhack 1 (model shadows):
No lightmap smoothing: 10.3fps avg
Lightmap smoothing: 10.1fps avg


and for the hell of it, here's how slow my colored lighting is
Viewsize 100 r_coloredlights 1:
15-bit: 6.2fps avg
18-bit: 6.2fps avg

Funny how a bigger lookup table for lighting makes no difference on a cacheless 486.

It's obviously bottlenecking in so many other places that this is making quite a small difference. Have you tried it with r_drawentities 0? That would help to isolate the performance difference from no smoothing a little more. Also demo2 is probably not the best choice for benchmarking this particular item on such a slow machine as the underwater warp will make up a large proportion of your frame time.
