Nvidia gives Quake II a raytraced makeover (on the Vulkan API)

Actually not necessarily...

(this pathtraced version is downloadable, there's a thread for it in Games too.
Author writes on the mods homepage he can't maintain 60 fps on his 2080Ti at 1440p.)

Interesting though and as is told up to 4 rays per pixel are used, hence the computational cost (plus denoising filter).

For comparison Metro Exodus uses 1 ray per pixel on Ultra RT setting (and 0.5 rpp at High).

Apparently the RTX demo shown was an updated version of this one including particles, roughness maps etc. and Quake 2 XP mod assets (hi-poly models etc.).

 

I don't know how to respond to that.

 

An engineer uses his free time to give a 22 year old game a cutting-edge feature FOR FREE, so a random guy comes and say "not impressed".

WTF?

 

The ignorance and lack of appreciation / understanding for what is going on in Q2VKPT is astounding.

 

I guess this is one way to show the tech in it’s full glory, except not... because the rest of the game is still in ‘97. Just shows that the performance hit of ray tracing needs a heck of a lot of work. It’s supposed to be a cheap and easy way to improve lighting, not a pathway to 50% fps.

 

According to what you just said, this does exactly what you asked.

After all, how often do you hear cheap and improve in the same sentence?

 

Cheap, as in not expensive, performance wise... (not the case yet) and easy, meaning easy to implement (maybe the case, but still need to put in plenty of work to make it look good).

 

I refer you back to my post.

 

"except not... because the rest of the game is still in ‘97"

I think you missed this part of the comment lol.

 

I missed nothing.

What's the rest of the game got to do with lighting, and why would it be cheap once the rest has been made expensive.

 

All I was saying is not a great example of ray tracing as the rest of the game is not realistic looking. Your also now just agreeing with me that ray tracing is expensive. I give up.

 

You said it wasn't meant to be expensive, not me.

So, now we agree.

See, I can play this game too.

 

It will be nice to play through Q2 again with RT feature and get a nice throwback just for kix.

 

Touché sir, lets agree to agree then.

 

I will have to see it in motion with my own eyes to really judge it. The early video shown before this really had issues cleaning up the noise of the path tracing.
Which is my biggest issue with RT aside from the huge waste of performance. Temporal artifacts and aliasing.

 

If you don't know why they chose this game for RTX showcase ray tracing - you probably shouldn't be here.
