What? You have lens flares even at 60fps with V2? I guess I have no other choice but to debug game code...
I'm not sure. Maybe V-sync wasn't disabled. So please wait.
Well, the easiest way to check is GLQuake timedemo IIRC.
I don't have Voodoo2 cable now so the check isn't easy. Unplug monitor cable, plug it to Voodoo2, then back...
Ok, the V-Sync is on by default
for a real Voodoo2. 59.9 FPS in the glquake timedemo.
If I disable it with FX_GLIDE_SWAPINTERVAL=0 - I get 143.4 FPS.
NFS5 have lens flares with both settings.
So - it looks like the source of the NFS5 lens flare trouble is nGlide...
I checked the logs. It uses double buffering but with W-buffer.
1600 * 1200 * 2(16 bpp) * 3(double buffer + w-buffer) = 11.52 MB?
