Polygon artifacts with n64 emulator using parallel plugin on libretro

I am having trouble with polygons drawing incorrectly. On Mario’s feet there are dark polgons drawn around the edges. In the golf game there are overlapping polgons. It looks like a z-sorting issue. I don’t see any options to address this issue in retroarch or in the parallel plugin options.

I can’t find anyone having this problem. I have tinkered with settings and gone back to defaults with no success. Any ideas?

I think some amount of Z-fighting is inevitable with increased internal res, as the precision just isn’t there in the original data.

I believe you are correct, someone in a different forum just showed me some screenshots. https://gaming.stackexchange.com/questions/387678/how-do-i-fix-these-polygon-artifacts-in-a-nintendo-64-emulator-using-the-paralle

Apparently Parallel is legit and these artifacts that I am seeing are not glitches and are in fact very authentic :slight_smile:

Yeah, probably one of those things the N64 hides with its low resolution on a CRT. Like the low poly Mario who appears when the camera gets s bit away from him.

I fired up Mario 64 on my real hardware with a big screen and s-video connection and those artifacts are present. I can’t unsee it now :*( but the parallel emulation is working great then! I was mistaken.

Thanks for the hardware comparison confirmation! That sort of information is very valuable :slight_smile:

Yeah how do you do polygon rendering my emulater is jaggy! I want to play n64 games

By “jaggy”, do you mean full of aliasing artifacts? If so, all 5th-gen consoles suffer a lot from this, with the N64 being the least affected. The only way to artificially counter this is to increase the internal rendering resolution, which may bring other problems along.

For a “modern” picture, it’s best to use HLE plugins (so no ParaLLEl), but these are also much less accurate. So you need to pick your poison between consistent or modern graphics. There’s no perfect solution, even considering all other retrogaming emulators.
