If you're not interested in using RT reflections & RT shadows (which you really shouldn't as RT shadows are severely bugged) , give this mod a try for lower RT cpu load thus higher fps when cpu bound. i also posted some benchmarks in the comments section of the mod. it adds between 5-20% to your fps depending on the number of npcs present in the area (less NPCs = more fps gained vs vanilla when cpu bound)
Incredible mod and works perfectly with the current version of the game (4.04).
It worked wonders, I'm using the "performance" version without Reflections and Shadows as recommended and it gave me around a 20% fps increase to an average of 82fps as per my AMD software (usually between 80-100fps depending on location/activity) and I haven't fully optimized my settings for performance, but rather for looks.
I'll also be attaching a test video I made, as well as a small showcase which even tho my software doesn't allow recording over 1080p60fps still (I believe) captures the beauty of the game and its scenery, which is just incredibly enhanced by Raytracing. I have since recording this video(s) additionally optimized and modded my game enabling HW for everything except Geralts hair, as it sometimes gives it a yellowish tint when in shade. (I recommend checking out the last 30-40 seconds of both clips for some beautiful sunsets)
Thank you for the mod and I hope others enjoy it as much as I do! :)
am i the only one who experiences micro stutters with this mod? its so annoying, the fps boost is good but the micro stutters make it a useless mod. patch 4.04 rtx 3070ti i7-12700h 16 gb ram
No, this mod won't work without the RTXGI Unlocker Updater DLL. The creator of it, Emoose, has not been responding for months. Once the RTXGI Unlocker Updater is updated to the 4.04 game version, the optimized Raytracking INI and my mod, Aio RT Tweaks, will work fine
emoose finaly updated RTXGI unlocker, now optimized RT mod should works also i have updated my AiO RT Tweak mod for even better performances, you can check it here: https://www.nexusmods.com/witcher3/mods/7979
It won't crash enymore, emoose before 4.02 update or hotfix has change in his rtxgi update auto disable feature that disable loading dll if you have game updated to newer version than the dll file. That's why is hard to tell if it's working or not on first look, only from fps difference when you applying rt tweaks, if you gain high fps then it's working, if not then don't. I think now is most probably not working if there is no difference in fps when using optimized rt ini, only thoes ini changes suffer from lack of working RTXGI Unlocker dll.

There is a memory leak present in the game at the moment, so it's probably that. There is a fix to do with changing your AF setting via the Nvidia control panel, but at the cost of visuals. Unfortunately it's the only solution right now. @hosq18 has mentioned it and provided a fix in his guide elsewhere if you want to try it out.
To be fair, I have tested and not really noticed any memory leak, so not sure of the validity. If it is real, it definitely varies heavily from system to system as I am generally able to play for over an hour with no performance degradation or weird increases in memory. Also, the supposed fix to do with forcing Anisotropic Filtering via Nvidia Control Panel makes the game looks horrendous and for some, would not be worth doing. I would look further into it yourself before making any major changes tbh
You just didn't trigger memory leak, ur GPU have to reach 95% VRAM usage at normal playthrough (then soon after ur GPU Bus usage will grove from 10-30% to 40-60% or some times to even 80% usage and your FPS will significantly drop). If you didn't using Sharpening then with AF + Sharpening to High looks acceptable good, yes it's still bit worse then without AF, but dude, with this fix for someone it's only posibility to play with RT On. For me this game even with this AF fix it's look far more better then without RT.
Here is a screenshot of HWinfo64 after playing for about 90 minutes (I only reset the average values timer after 20 mins of gameplay). Running at 1440p DLSS Quality. I rode all around Velen from Midcopse to Oxenfurt and then to Novigrad where it is most demanding, then to Crows Perch and back to Midcopse. I experienced none of what you describe. My VRAM usage hit 94% max at a certain point but always dropped back down to around 8GB usage average (I have 10gb of VRAM). GPU bus load maxed at 35%.
Now I am not saying this issue does not or can not exist, YOU may be experiencing this problem on your system*, but to recommend to everyone (either via comment sections or your All-In-One mod page) that they apply this fix that will horribly deteriorate their IQ for a problem they may never run into... seems a little heavy handed, no?
*(Unless I'm mistaken, I believe you've mentioned elsewhere that you run an older GPU which has less VRAM and specifically only runs PCIe 3.0. Might this be the cause of your issue, rather than something that everyone will experience?)
I'm sure it may happend to everyone, like you wrote, you did not trigger memory leak becaus ur VRAM usage have to reach 95% VRAM usage ( = or over 95%), you reach 93,9% and thats why u didn't trigger memory leak yeat. i have found another Memory Leak Fix (for any GPU) My Mobile RTX 3060 GPU is yonger then ur desktop RTX 3080 imao... and that's why it has less VRAM it's much easier and faster for me to trigger this memory leak. Yes it use PCI-E 3.0 beacuse of AMD realeased this GPU that way, but even if ur GPU has faster PCI-E bus this leak will still exist, only data transfer across PCI-E to ram/virutal mem. will be faster, but still many times slower then VRAM itself, thats why everybody will notice FPS drop, less or more damanding. You have to play longer to finaly trigger it, run around Novigrad center or find other havy vram usage places, try reach near maximum VRAM usage. After this playthrough save ur results maximum GPU BUS usage and avarage FPS and compare to playthrough with memory fix mod applied.

I think it is not working for me, probably because RTXGI Unlocker has not been updated.

ran a few 100% cpu-bound benchmarks at 1080p high + dlss(P) + OptimizedRT(P):
4.01 :
Kaer Morhen : avg 68.3 , min 49.3
Novigrad : avg 43.2 , min 32.8
4.02 :
Kaer Morhen : avg 72.5 , min 53.8
