Performance drop with 2.21 - RT, DLSS etc

I have noticed performances drop since the new patch has arrived. Even if frame generation declares frames above 60, sometimes 120+, latency is so ridiculous (sometimes 100+ ms) the game moves in waves like a bride's walk, and nevermind combat, even driving is impossible. Mods are a non issue, tried with a clean install and a file repair as well. I believe I have the iron to run the rig at top performance, and that's what I am aiming to.

DLSS smudges NPC faces and morphs them like the infamous Ecce Homo, and cars look like bad Midjourney prompts. All in all, I find it's best without any kind of frame generator. The number of duplicated NPCs is also staggering.

The only thing that helps for a while is reinstalling the latest Nvidia drivers, and that helps for a few hours/game sessions, then everything falls back to the bride's march.

So, I went and made a clean install again, and run some testing.
The application never goes beyond a certain RAM or CPU usage if you do not force it to. The top it used, RAM wise, is 57% RAM total, which meant it left 9GB untouched. I had to go and manually kill every app including NVIDIA and discord etc. Generally speaking, as per my experience, it will also try and float around 50% CPU usage if possible.

I also went and made some changes at NVIDIA parameters, setting unlimited cache for the shaders, low latency mode on app, energy saving off to max performance, and CUDA system memory fallback since I have to spare. No idea if they changed anything, but I wanted to make a point. Oh, also set the .exe to run as admin, and tried several times to play around with priorities.

As per my configuration, Frame generation is suicide. It is never convenient, and introduces such a killing latency that makes whatever astronomical fake frame rate useless. Keeping it off is standard.

After all this fiddling, the most fluid combo I could find is DLSS on quality, 0 sharpness, no reconstruction, no ray tracing, crowd density high, and everything else at max. CPU manages to get past 60% usage, and RAM usage floats around 50-60%. Benchmark floats around 140-110 FPS and most importantly never stutters, nor in the bend inside the bar past mama Welles, nor by crossing the street outside.

Switching on ray tracing means getting much lower CPU engagement around 40%, and RAM stuck at 45%. Framerates are really good above 70%, but the stutter is annoying. This is surprising because it's as if the GPU needs to do it all without relying on neither the CPU nor the RAM (and no, I set the latency mode afterwards trying to make ray tracing work, to no avail). So no matter how much I tweak, ray tracing is out of my reach, and frame generation is useless.

After the benchmarking trials, I decided I can keep all the app open since I have 9GB unused for RAM. Set AMD SMT on, and HDD off since I have resources to spare.

I was hoping that for the iron i've bought I could get the best configuration, especially since I have to fire 1080 pixels, we are not talking 4K here. I have read around that there's much that can be done about graphic optimization yet, and since CP77 has become the 2020s benchmark like Crysis used to be once upon a time, it might be worth keeping on tweaking on those graphic options and try using more resources as pc become better and better.

Of course im more than open to any suggestions about any other configuration to try. Maybe this can be of help to someone in a similar situation.
 
I'm having frame rate issues since the latest update and I never had it before. It was so bad I had to lower filtering a bit and even shadows, to be what it was a month or two ago.
 
Forgot about this thread...
Conversely, DLSS 4 ahs solved many issues I used to have.
With the upscaling I can comfortably get to 60 FPS and tolerable latency (35-75ms) with ultra settings + RT + PT.
Frame generation does increase the little number in the upper corner but I fail to see any improvement on screen, and since it fails to reach my monitor's refresh rate (110FPS vs 144MHz) I keep it off.
I suffered some serious tearing which I managed to tame with V-synch first and then G-synch (my monitor is not G-synch native but managed to convince it can do it if it tries, go V279 go!)

Just a slight tangent as I'm not sure it has anything to do with your issues, but might be relevant for others. Windows Update 24h2 has been causing significant frame rate issues with a wide range of games (Elder Scrolls Online, which is hardly the most graphically demanding game of all time, was running as if through a zoetrope for me on a 4070 ti Super), as well as wider stability issues with windows, audio problems, etc.

So, just in case, check it's not that. I've rolled back the update and my system is back to normal.
 
dealing with DLSS surely you're also upgrading the .dll in the game files as well.
 
posted another thread just now, but I've been having an issue since the update in which reflex appears to be incorrectly limiting the framerate well below the refresh rate of the screen. on a 120hz screen, the game will start around 110-120fps as it should, but gradually drift down to 90fps before staying there like there's a framerate cap regardless of the intensity of what's on screen, and the GPU is clearly being underutilized per RTSS stats. Toggling vsync/frame gen/framerate limit settings a bit points towards the culprit being reflex.
 
There's something going on and I dont know what it is... I have gone through several nvidia driver reinstallations in order to have good frames. Fact is, after a few games the FPS start dropping and the stuttering gets worse, so I have to reinstal to reset the thing.

are you using DDU in safemode when uninstalling the driver? Also blocking Windows auto driver installing?
 
Reflex is broken with the new Version of DLSS FG. My 4090 sometimes drops to 80% Utilization despite not hitting the normal FPS Cap of 116 on my 120hz GSync Monitor, hovering around 90. But I think thats an NVIDIA Problem, not sure if CDPR can do anything about it.
 
Found a way for a massive improvement with my AMD CPU (see my specs on OP). Enabling Gaming Focus on the BIOS more than halved my latency and pushed my FPS even when new items are introduced, i.e. in the benchmark I usually had a spike in latency above the 100s when the camera flies over the barbed fence and crossed the road when the game creates the NPC crowd at the same time with the raytracing of the sun on the buildings around and the particles of the plants: this time, my latency stayed below 30s at the worst.
