Raytracing Mod with 30-50% Uplift

[AbysmalEnd]

This amazing modder has made changes to the RT in the game by dialing it to perfection in the ini files. he made two styles, one for quality and one for performance while still being able to maintain simliar levels of RT quality. on my 6900XT with a 5800x with all RT enabled with optimized settings at 4K with FSR set to ultra performance. I would get FPS in the range of 50-67 depending on where I am. Using the Performance RT MOD i can now set FSR to performance and get a locked 60FPS while raising other setting. its truly amazing and I highly recommend it.

Remember this is only for RT.

in this case it doesn't really matter though, the cpu usage is far too low, even according to their own recommended specs

Did you check the load on single threads?

In case of The Witcher 3 with my new cpu now, check all cores - despite having 8 P cores above 50%, 2 of em are maxxed out.

This. Staying at Novigrad right now and only 2 cores of my 12700K are overloaded. The rest are touching the grass somewhere.

Applied the performance ini...

Specs:
GPU: 3070ti
CPU: Ryzen 5 5600
RAM: 16GB 3200 MHz

Settings:
2560x1440
RTGI: ON
RT Ref: Off
RT Shadows: Off (too much pop-in for my liking)
RTAO: ON
DLSS: Balanced

Shadows: Low
Terrain: Low
Foliage Distance: Medium
Grass Density: Medium
Textures: High
Water: Ultra
Object Detail: Ultra

I also set TextureMemoryBudget=4096 in the ini file, not sure if this actually does anything but some old threads for DX11 version mentioned that it corresponded to VRAM. Mine was very low for some reason.

Getting 70-85 fps in Velen now, still down to around 55-70 in little villages (haven't gotten to novigrad yet, but I fully expect it to be a slog). I was definitely struggling to maintain ~65 fps before. Skellige on an old save was around 90 fps, which is awesome.

This is what I've personally setup as settings which maintain stable high-ish FPS while trying to minimize visual impact. The biggest impact to visuals historically have been textures; Terrain detail seems to be bugged (?) and shadows don't make an enormous impact visually. Kinda strange that since DX12 Textures is such a big performance impact, but whatever.

is it worth it though? you set everything else to low and medium is it worth the the hit on all the other graphics options for RT

I am in agreement btw, just so you know.

the cpu utilisation in the game is far too low, it is unoptimised. they recommend a 3700x for 4k+RT yet cpu's better than that struggle.

Id say no. He didn't say what resolution and if its 1440p he should be using performance DLSS mode.

I never drop below 35, even in Novigrad, with everything cranked to highest. Outside is same performance as him pretty much.

3070
5800x3d
32gb
1440p
Performance ini mod

[Strider]

Oh yeah, duh forgot resolution. It's 1440p. Like I said, the things I cranked down make less visual impact. The biggest factor for visuals are RT, foliage and textures. I only really make sacrifices for foliage and textures and it runs at 80-90 fps. Performance DLSS is way too blurry for my liking. Imo if you're doing perf dlss, you might as well turn your textures and shadows down because you're blurring the image quality way past what gains you'd make in FPS anyway.

Also why tf would you ever want to play the game @ 35 fps just to have some more grass?

Performance mode is officially recommended by Nvidia in general for 1440p. It is in all official documentation.

I can confirm that it does not look blurry in this game, and like many others offers the best performance gains with respect to iq.

Nvidia focuses almost exclusively on the performance modes for dlss development, because that is where the iq gains need to be made.

Maybe try another dlss dll because the one the game came with isn't the best?

If you need to use anything below quality for dlss, maybe balanced, drop the settings and resolution first, the game will look better, performance and godforbid ultra performance drops the games resolution down way to much and it loses a load of detail needed to upscale it and work its magic with.

In general, each step drops it down 1 'catergory' of resolution.
So, 4k on quality renders it at around 1440p, on balanced, 1080p, performance 720p and ultra performance 480p

If you are running 1440p at performance that's essentially trying to upscale a 480p image, which looks awful, just try dropping 1 level at native or quality, you'll end up with similar performance but it will look better.

Edit.

Make sure you check your gpu usage, the game with raytracing is causing my 9900k at 5.2GHz to be the limiting factor with my 3090 as raytracing seems to require far more input from the cpu than it did originally.

[Snip3rW0lf^.]

with the first person view mode and this ini file. TW3 egins to be a good game. The last thing which sucks is the gameplay omg. How is it possible to make such bad comats... A good game anyway as concernes the writing and the landscape, moreover with this version.

You do not understand how DLSS works.

1st it is a reconstructive technique, meaning it pulls data from "3d space" (frame\buffer data) to draw the image. The image is then reconstructed as a 1440p (or whatever native res) image. Obviously this comes with a lot of artifacts that are being actively worked on by Nvidia.

Each mode of DLSS works with a base resolution derived from the native. Therefore, given that performance mode is 50 percent scaling, it is drawn at 720p. Not 480p or whatever you think you are talking about.

Now, ask yourself two things:
1. Couldn't 720p as a base resolution look nice considering 720p doesn't look that bad? (Yes)
2. How can nvidia improve DLSS, which is designed for performance, from an image quality perspective? (by focusing on developing performant modes)

You and many others cant seem to grasp that DLSS improves in IQ, the larger the native resolution is, because it works with a larger base resolution. At 1080p, 50 percent scaling (540p) is going to reconstruct like **** no matter the scenario, so you choose the highest quality DLSS mode. HOWEVER, moving on to 1440p this base resolution in performance mode is now 720p. The same resolution QUALITY mode is at 1080p! If thats not food for thought idk what is.

Telling people to just choose a DLSS mode without any real information is telling people to leave performance on the table. *This is all why nvidia states on their own site that performance mode is generally recommended for 1440p gamers. Also why imo 1440p is the true sweet spot rn.

I'm just lost at folks seeing 2 cores being tapped out (and the rest going begging) and folks thinking that 'I just need to tune my RT performance and I'll be all set'.

My GPU is not *remotely* being utilized right now, so tinkering with its load will do next to nothing for framerate.

Until CDPR optimizes the core usage, using this mod is like switching from regular petrol to premium petrol... for a car that only has 3 wheels on it.

Fix the DX12 CPU allocation and we'll get a massive boost to framerate, which in turn will make RT playable on my 3080.

How I explained it is pretty much accurate and very obvious if you look at the images and 720p has never looked good and there is simply too little data to pull from for a good ups ales image, if you think it does, I am guessing you also think motion blur and vsync are good.

Performance looks like poop and if you are using raytracing, you are likely cpu bound at that point rather than gpu bound anyway.

Yep the game is very cpu bound now, even more so with raytracing, my 3090 is often at 70% utilisation or less with raytracing on, this is with a direct die watercooled 9900k at 5.2GHz, raytracing seems to be the real area that makes my cpu show its age now.
