AmiQuake new 68k Quake Port for AGA/RTG

[Reido]

Video quality is probably too poor to be of any good to you. Looks amazing on my CRT, doesn't record so well though!

Cool, could you tell any difference in the quality of the sound effects? The sound should be a little clearer with this new build. Also I've doubled the amount of particles and both of these improvements will hit performance a little unfortunately....I'm working on adding a bit more assembler to negate this (hopefully).

Recently had some time to kill so I thought I'd revisit some of my old Amiga ports and see if I could improve them but I only have WinUAE to test with so you don't always get an accurate idea of performance.

Update: v1.16 in the Zone for testing. This version has some extra assembler (by John Selck), hopefully this will bring some slight performance improvement.

There's some distortion of the background sound effects, mostly sporadic (sounds like a crisp bag being squashed briefly), this would be an example of the worst of it. This is V1. 16, same with V1. 15

Original V1. 14

I honestly didn't notice much difference in the performance, all good.

[NovaCoder]

OK thanks, I think some of the updates to the sound effects are causing issues... I'll take a look.

Update: I think I've fixed those sound issues and also increased performance of the particle implementation.

Can someone test on real hardware please....hopefully I haven't broken anything else

v1.17 in the zone...and v1.19 uploaded to AmiNet

For anyone interested on my level of hackery on this port, compare the original WinQuake source with my modified code.

Some tests by the Vampire lads!

I had a quick go on v1. 17, looks and sounds great! I'll check out V1. 19 this eve.

[trixster]

is it possible to get m_filter added?

[nujack]

Any chance to get 3D-Support for iglasses?
3D-Mode can be activated via lcd_x 1.0 on console(http://www.stereo3d.com/quake.htm).
Would be cool to play it on my A1200/060 on AGA interlaced mode.

No sorry, that would be too much work

m_filter gives option to add mouse interpolation, default is set to 0 =off, values higher will enable it.

Oh OK, I'll take a quick look.

Has anyone notice any speed improvements with v1.19? Hopefully it's not slower

[digiflip]

thanks Novacoder, works great on replay with 060 at 80 mhz, will there be rtg in a update?

Are you sure? The command lcd_x is already available and afaik you need an interlace-mode for the i-glasses to get a stereoscopic effect (NTSC/PAL-Highres-Interlace should be fine). Is it really much work to support these 2 gfx-modes in your port?

Yep I remember commenting out a lot of that code and don't want to try and put it all back in (could break something else).

[eXeler0]

@Nova, does this version have a 4096 units size limit for the BSP/ map?

I assume so, it's based on WinQuake which was the original official source port from way back in the day. I have not done anything to improve functionality, I've actually been removing functionality to improve the speed on real hardware

This version has fixes to the maths lookup tables and also should have better sound, particles and lighting. Not sure about performance though as I no longer have a real Amiga to test on.

shame you don't have an Amiga but we still Love ya Nova

Thanks mate

I understand.
Would it be possible to enable NTSC/PAL Highres interlace as alternative screenmodes? I would try out if stereoscopic picture is available with that.
BTW there is a gfx-failure on the left side which appears the whole time(tested on A4000/060, see attachment). Performance is very good.
