42bs Posted June 3, 2022 Author Share Posted June 3, 2022 Acutally, I find the "flight" quiet impressive even with avg. 42 polys/s frame. A grep in scene.S revealed the max. is 164 polygons. 1 Quote Link to comment Share on other sites More sharing options...
agradeneu Posted June 3, 2022 Share Posted June 3, 2022 (edited) Yeah looks impressive, altough it's precalculated and thus a bit cheating involved Edited June 3, 2022 by agradeneu Quote Link to comment Share on other sites More sharing options...
42bs Posted June 3, 2022 Author Share Posted June 3, 2022 3 minutes ago, agradeneu said: Yeah looks impressive, altough it's precalculated and thus a bit cheating involved Still the original was on an Atari with 8MHz and is from 2000. Demos live from "cheating". It is all about the impression. And: It is a good benchmark for a poly routine and other stuff. Let's take it this way: If you want to make a 3D race with fixed perspective (never played wipe-out),a pre-calculated track seems to be a fair compromise. I mean, you also "pre-calculate" the different positions of a sprite. 1 Quote Link to comment Share on other sites More sharing options...

42bs Posted June 6, 2022 Author Share Posted June 6, 2022 Further optimization on github. Now it runs in 60FPS (runtime is 1800*0.017ms), but calculation takes only 17.6s, that's 4280 polys/s or 71 polys/frame. 4 Quote Link to comment Share on other sites More sharing options...

DEATH Posted June 6, 2022 Share Posted June 6, 2022 also on my Jaguar there is no sound on the right channel Quote Link to comment Share on other sites More sharing options...
42bs Posted June 6, 2022 Author Share Posted June 6, 2022 30 minutes ago, DEATH said: version/option without Vsync Makes no sense for this scenario as drawing takes more time then the VBlank which means the screen gets scrambled. 27 minutes ago, DEATH said: also on my Jaguar there is no sound on the right channel Strange, but noticed this also on one of my SCART adapters. Maybe LSP mixing is wrong. 33 minutes ago, DEATH said: Skunkboard the screen background is not black (it makes a kind of white and pink grid I will try with my Skunk.

42bs Posted June 6, 2022 Author Share Posted June 6, 2022 As I wrote: 17.6s for the pure rendering w/o V sync. Quote Link to comment Share on other sites More sharing options...

42bs Posted June 6, 2022 Author Share Posted June 6, 2022 IMHO the new PC style thinking of FPS makes no sense, since redraw during displaying the same screen results in scrambled display. I tried to blit the final screen to the display buffer, but for this the bus is to slow. So, there is not just tearing as with modern gfx cards. Anyway, it outperforms 3DO ?
