nGlide vs true Glide

Postby shoober » Tue Jul 16, 2013 6:37 pm

This might be a silly question, but I was wondering how accurate nGlide emulates the Glide API. I'm really considering buying a Voodoo5 5500 and building a PC for Glide games that uses the SFFT drivers. But, if nGlide accurately emulates the Glide API, then I will just stick with nGlide. So how accurate is nGlide?

nGlide 1.01 compatibility level is about 94% with all Glide API applications (without counting 8 statically linked DOS games that cannot be wrapped and assuming you're using fully compatible DX9 card). The goal for 1.02 is 97%.

If you plan to build fully Glide API compatible machine and high resolutions isn't something you're interested in your best bet will certainly be original hardware. But beware, Voodoo5 alone + Windows XP won't give you perfect compatibility. Early Windows Glide games won't work with V5 as well as those 8 statically linked DOS games. For them you'll also need Voodoo1 + Windows 98 + DOS.

Oh snap, I didn't think about that. Thanks for the heads up. I've been wanting to also make a dedicated machine for DOS. Now I know which video card I'll put in it.

Is nGlide even considered an emulator? It kind of reminds me of WINE, since WINE translates Windows API calls, and nGlide translates the Glide API to Direct3D calls. Is this a correct assumption? If so, how accurate is the translation? Would games look any different if you played them on the true Glide API rather then nGlide (besides the higher resolutions)? Even the smallest difference I would care about, since I would consider myself a purist. I want a true authentic Glide experience.

Besides that, your program helped me play Slave Zero with 32-bit color on Windows 7. Slave Zero will not let you choose 32-bit color unless your graphics card supports 32-bit Z-buffer (which no modern cards support anymore), so thanks a bunch.

nGlide is a Glide API wrapper, not an emulator.

Slightly yes, but in most cases you won't even notice the difference.

Emulators (and related stuff) are by definition not authentic, you'll have to build a retro PC for that.

In all intent, wrappers ARE hle emulators.
