Hi lads,

well this talented guy seem to have made the very first full implementation of RTX technology.... in a 20 year old game! And it looks awesome too!
You know where my thoughts went immediately after :rolleyes:

Wow !!! That's very nice. Do you really think it's applicable to GPL ? That would be incredible !

"full implementation of RTX technology".... er, no. Follow the link below the video and read. He had to rewrite all of Quake 2's graphics code, and it isn't even complete. No particles, for example. The only reason this example was possible is because Quake 2's source code is now open source. I can't imagine Papyrus opening up the GPL code like that any time soon, even though it's 20 years old.

Sorry to put a dampener on it, but I don't see any way that RTX path-tracing (not ray-tracing) will have a major impact on GPL, and IMO it won't be possible to get a "path-traced" version of GPL.

Especially because they LOST the code!
I remember they stated that in the early development of iRacing; was a shock to me.

Losing the code as I recall it was due to computer crashing shortly after GPL's release.
Or somehow with the collapse of Papy.

This is probably what has kept Grand Prix Legends as it is today.
With no source code there is nothing to own except trademark and copyright on a hollow shell.


:D

I don't know about it being lost,this is something I found on line from 2004.
Papyrus Founder Buys Back Source Code, Goes Racing

13



Posted by simoniker on Friday July 16, 2004 @03:16PM from the legends dept.


Thanks to The Pits messageboard for its post noting, via this month's PC Gamer magazine, that Papyrus co-founder Dave Kaemmer has bought back "all of the critical [PC racing sim] source code" from owner Vivendi Universal, following VU's closing-down of the Grand Prix Legends and NASCAR Racing developers. Kaemmer"teamed with Boston Red Sox owner John W. Henry"to launch this new venture, and intends to provide"high-end driving sims", seemingly involving personnel from the Project Wildfire NASCAR modding site.
So perhaps the source code does still exist but just isn't available .
this is the link but there isn't much more to it .  https://games.slashd...ode-goes-racing

IIRC was David himself that answering a question about using GPL code for iRacing development said that GPL code was lost, gone for good and they were using NASCAR racing alone for the online bits.
