DOOM II RAY TRACED Mod vs Vanilla - Graphics Comparison

PT in games like Doom 2, Half Life and Quake 2 can take the atmosphere to a new level, but it also shows the compromises that have to be made in order to even run PT in such old games. Shadows are very blurry and undefined in all three games, despite the use of PT. What's worse there's noticeable time delay when lighting changes and there's also ghosting. In many places lighting has noise and flickers, so even strong denoiser clearly isnt enough (maybe Ray Reconstruction would help?).

I think with current GPUs the best way to use RT is in a hybrid way like in Metro Exodus (standard edition). Thanks to RT, the lighting in this game is no longer flat, shadows are still clean and sharp, and there's no ghosting. Performance is also much, much better compared to PT, as I can run Metro Exodus at 85-100fps even at 4K without the help of DLSS upscaling, which is not possible in PT games.

In Cyberpunk you can choose RT or PT and only RT does not ruin the experience. With PT, some places are just too dark, human faces can look strange, and of course there's some very noticeable ghosting (especially in areas lit only by indirect light).

I'm playing Alan Wake 2 right now and the game seems to be using PT in a good way, as the lighting looks natural compared to PT off and there's no noticeable ghosting, but there's still some noise in the lighting.

For the time being, PT is just a technology preview and we are still a long way from PT becoming a standard technology in games. At this stage it's better to use a hybrid RT approach IMO.

It's...interesting..

However, the bounce lighting is excessively dark and contrasty, giving it a weird appearance (and yeah the blood doesn't help). It doesn't need to be completely realistic, but at least a stylistic improvement.

is this an option in the doom/doom2 package that just released or only a PC mod for the steam version? someone said it requires the steam .wad file? I'm pretty sure I have doom in my steam library but would be interesting to see how the xbox handles it.
 
Amazing. I just installed it with the dlss options.
I never played a 3d version of doom before. It was a bit jarring having mouse look in 3d. Although I ran a mod for Dark Forces that did the same thing. Guess this has been a thing for years?

The rtx was really good actually, and I liked the blood. Don't like it , why not try making it yourself, its a mod, not an offical release.

Thing that gets me, how are modders able to do this but the dev team porting doom 1 +2 couldn't even get the soundtrack volume and proper rumble into the switch version when it was in the previous engine.

Thanks for showing this OP! Really fun!

What detail though? Come on, the sprite was just low resolution, but the voxel version transformed it all in boots made of boxes 😂.
🤷‍♂️

Plus the original you posted is not with RT. I said the original sprites would look worse under RT lighting than the voxel models under the RT lighting.



They are just pitch black sprites under dark scenes.

Can be solved, but it does not make the voxel characters good looking :).

probably not, i think the 2d sprites would cause issues with the shadows and the lighting.
It worked fine in Doom 1 RT.
The voxel character do look really jarring with the rest of the art - I'm not a fan either.

Than post the solution to us. Options are always welcome.
Voxelize/polygonize a high res model. Downsample to lower-res sprite on draw to keep the og. look without looking like poor man's lego.
It's work - but then so was voxel models in the first place - they just don't look great, especially as long as gameplay maintains 8 direction locomotion (that bothered me from the first time they introduced them - it defeats 50% of the benefit of having them voxelized).

2016 was 8 years ago

:pie_lcry:
It's not just FPS either. Played this Aliens RTS the other day and it's like ... cutscene every 30s - how is this even considered playable anymore let alone an RTS...
