Duke Nukem 3D new version for 68060

[Cosmos Amiga]

A new version of Duke Nukem 3D v0.4 is available for 68060 on my forum (the GHOAC for Good Home Of Amiga Classic) : http://www.68kforever.com/forums/showthread.php?1-New-version-is-coming

Some improvements :
- all mul & div 64 bit removed, much better for 060
- the Duke3D: assign removed
- the Duke3D: assign for AmigaSetup removed too
- added a $VER Duke Nukem 3D 0.4 by Dante, Bifat and Cosmos in the main .exe


I'm looking for good coders to optimize the mul64 routines and later the div64 if Frank agree : you are welcome !

Cosmo, could you upload it to aminet?

Thanks, Amiga deserves decent version of Duke Nukem 3D

Ok, I'll put it on Aminet !

WOW! The difference!

Didn't I already port this years ago?

Unbelievable!, and all thanks replacing mul/div 64 bits instructions?
Good work indeed!

The video from NovaCoder seems a slower version; much different rig setup?

The Nova version is only AGA, that's why I updated the RTG Dante's version

My video show a 3dfx screen !

I guess a problem somewhere : why I got only 1 fps with the v0.4 ?
Last 68060.library 46.16 installed with Rom2Fast...
I saw another video with this time an Apollo 1260, and Duke run fine (https://www.youtube.com/watch?v=zRdgaRoKdJc)

The next v0.5 is coming soon with a faster Smul64 routine using now the Fpu

Thanks to Matthey for this help !

Using FPU will ruin this version for Vampire owners or not? (Just curious)

Still use the v0.3 on this A600 accelerator...

Explanation : the instructions mul64 & div64 are NOT inside the 68060, so the 68060.library emulate them, and very slowly...

I replaced all of them with instructions who are really inside the 060, so no emulation anymore = big speedup... Oups, still one mul64 into the v0.4, sorry, was in the libnix... The v0.5 will fix that...

I have a new version of BlitzQuake who have the same problem but with sinus & cosinus : I get now 4 fps faster !!

I don't understand - aren't we talking C code here, or did Dante optimize the whole thing by porting parts of it to ASM? Libnix certainly is C.

Ok, I'll put it on Aminet !

That requires honoring Duke Nukem's license (GPL). I'm not sure how to do that, if you just patch other people's binaries. But at the very least, the license needs to be mentioned and you need to include an offer to provide interested parties with a way to easily duplicate what you did. I doubt that "I replaced all mul64/div64 instances with 68060 friendly opcodes" will suffice...
