Generally I’m impressed by the performance. It runs at around 90-160 fps, which is nice but a very wide spread. Oddly when zooming in the FPS is lower than zoomed out. Also, in the city it’s usually even lower than during intense fights.
My trouble however is that often there are small microstutters when traversing the level but mostly in the main city. They are very small but noticeable, probably like 1-3 frames long? It’s difficult to say if there is a frametime spike or framerate drop because the framerate is rarely constant. The stutters somehow feel like vsync stutter but that can’t be since I’m using a gsync monitor and my fps are always above 90.
I’ve locked my FPS to 120 like I have read elsewhere that this would solve the issue but it didn’t help.
CPU load hovers around 50-80%, GPU 60-98%
Game set to Ultra, 1440p, nvidia low latency on, 100% resolution scale
DLSS and frame generation OFF
Latest drivers for everything, all unnecessary background applications including brower are closed.
I want to bring this topic back to life, the same thing is happening to me… Will it be addessed in the upcoming patch? I have a 4090 and 7800x3D now i know there may be other factors to this… but its very frustrating to say the least as the game is amazing.
Game is a VRAM Killer. A German site analyzed it, starting from 16GB you have no limits in 4k. Everything below, you may need to reduce texture quality or uinstall highres textures from launcher.
I have a 4090 + 13900K +32GB RAM and no issues here. Limited FPS to 144, unlimited its >300 fps on 1440p and a power waste. But I’m running it from my M2 SSD, not SATA.
When I remember correctly, D3 had the same issues on release. Without SSD it was not playable.
Its a strange one, ill be fine and then i wont be fine… now i dont think this is down to a mem leak as it can happen on game startup, i too have my FPS capped to my monitors refresh rate but I still when moving will get frametime spikes.
But yeah, below 16GB your mostly sh… out of luck in D4.
I’m on 8GB VRAM and playing with high textures, everything else maxed, DLSS quality from 1440P.
It runs mostly ok now, though there’s still some stuttering but not gamebreaking anymore.
The frametimes in this game are really bad, even if i set everything to low, i get small spikes when just moving around in town.
12GB is fine for ultra textures on 1440p. The game uses about 10 of 12GB VRAM. There is no crash or other stutter or any sign of texture loading that would suggest it’s a texture problem. I think this is more likely either a network issue because it happens more in cities, or a asset streaming issue.
Is your framerate completly constant without fluctuation when you check with rivatuner overlay or similar? Don’t use the internal FPS counter of the game.
Digital Foundry and several hardware and games magazines say otherwise.
They all say using ultra textures with less than 16GB of VRAM results in stuttering.
But then again, there is always microstutter even with everything on low and 720P
Yeah, no matter the settings the stutter can and will occur, i have found however leaving the game and coming back seems to “fix” it… So to me this seem Diablo related and not PC.
Of course, it is caused by their engine not being optimized for PC memory management cause they developed for the consoles first with their unified memory handling.
This is the main cause for many bad PC ports in the last 6 months.
It can be fixed if they put in the effort though, so let’s hope that it will be patched sooner than later.
What resolution are you running?
Ultra textures enabled?
DLSS or native?
Anyways, there’s many posts from people with 20/24GB cards, AMD & Nvidia, who are having problems with VRAM running full and causing stutters and crashes.
There’s no denying that the game’s memory management on PC is just bad.
There are many reasons it can crash. I agree the memory management is terrible. You can check FenrisDebug.txt, it will eat up all your ram and create a pagefile the size of ram after a while of playing. This is abnormal and no other game I own does that.
I tried a lot with different settings. The only way to make it crash (for me) with an error “out of vram” or something is using DLAA or Frame generation. But even then it’s rare that it will crash.
I’m running 1440p with DLSS Quality, everything else on ultra on a RTX 4070 12GB and 16GB system RAM. I can run it without DLSS too without crash.
I must also add I don’t play more than 2-3hours in one session. So maybe crashes are more common when you play longer sessions.
