Rise and ray trace, Mr Linneman. The DF team unite to test out a true PC classic in co-op, only this time with Pascal Gilcher's ray tracing mod enabled. John, Rich and Alex enter the fray with a multitude of GPUs too; an RTX 2080 Ti, AMD Radeon VII, and GTX 1060 - showing just how much it takes to make this a reality.

These co-op raytracing videos are the worst way to discuss raytracing on video. A 1 hour long video made live about graphical features toggling things on the fly. Just doesn't give credits to the graphics especially with the split screen.

It should be analytical videos that take the time to browse through benefits and cons. Explains this isn't a fully implemented Raytracing system but a overlay global illumination done by ray tracing.

If HL2 had no light maps and the game was rendering a full lighting of the game like modern raytracing it would look amazing. Realtime light bouncing and shadowing would make the game look great.

Watched for a while and the tech is quite impressive to see (if a tad limited) but I'm gonna have to echo @Aintitcool - the co-op run through format of having to physically move three dudes though the game feels slow and clunky compared to the precise and highly produced nature of DF's usual analytical content.

I feel like it could have been compressed down quite significantly time-wise.

80% gpu use on 2080ti for half life 2. Barely any difference lighting wise and atrocious shadows. yeah...

But co-op mod looks great.

I don't get ray tracing. Like, so what? For how power hungry it is, I would rather have better physics....

I honestly can't tell the difference. HL2 is perhaps a bad example to show ray tracing.

Quake II is much better at showing the tech IMO.

I don't see the point of what they're doing, it's doesn't change crap in any significant way. The Nvidia Quake II demo was more interesting.

Looks great, but I wish there was an official patch for ray-tracing support, I'd (and I'm sure many others would too) definitely go back and play these old games if they did that...

Every technology has to start somewhere. I don't think DF are arguing for this as the go-to way to play these games right now so much as showing off something cool that's still developing.

Sorry if I sounded dismissive. Like, I can see the benefits, but from what I hear about the resources required, I would rather they put the effort into Physics where there would be more bang for the buck, if you get me?
