I have a fairly powerful rig that, when I bought it a year ago, allowed me to run the game at max settings (1920x1080, DLSS, Ray Tracing on) with a solid 150-200 FPS. Unfortunately, for some time now, I’ve been experiencing massive FPS drops - or rather, “lag spikes”—where the FPS count remains high, but the game stutters horribly. This usually happens in areas with lots of NPCs, like Paris (bar area) or Mendoza. For example, when I launch fireworks in Paris, my FPS drops from 150 to 30 (!!!).
I don’t remember it being like this when I first got my PC—everything ran ultra smoothly. The worst I noticed was a slight drop from 150 to 120 in Mendoza. But now, in some areas, the game is nearly unplayable.
You can try to reinstall your GPU driver by clean install, using DDU utility or clearing shader cache.
I would recommend both, but you can start by simplest - the cache, and if it won’t help, do the reinstall procedure.
Cache can be found here:
C:\Users\xxxxx\AppData\Local\IO Interactive\HITMAN3\
Simply delete this HITMAN3 folder.
If it does not help, download the utility, clear the cache again and reboot PC in safe mode.
In safe mode launch the DDU and follow onscreen instructions.
After job done, boot PC in normal mode (DDU will do this automatically, just don’t forget to untick safe mode option if you’re using msconfig).
When PC boots up normally, install the GPU driver using clean install option.
I always try to keep my graphics card drivers up to date, and after each installation - which I always do as a “clean” install - I also run programs like CCleaner or Revo Uninstaller to remove any leftover files. So in that regard, I always do my homework.
However, after clearing the cache from the folder, I did notice a significant difference. Lag spikes still occur, but much less frequently and not as severely, and my FPS increased from 90-120 to 150-180 in crowded areas (normally, with this setup, I get up to 250-290 in less demanding locations).
I know what you mean, but the driver could have installed with errors or be corrupted etc. so if you feel something not right, it’s better to do described procedure.
Clean install within the driver itself might not be enough. The utility I linked you to unistalls GPU driver conpletely excluding any errors which may occur
Those are garbage if you ask me. Sometimes they could do even worse.
Advise you not to use them whatsoever
Good to know something did get better
I may suggest, that because game caches itself again.
It should disappear once the game desides it’s nothing more to cache
I had the same problem a few weeks ago, but it could be many things…
In my case it was something related to a too-much bloated OS or something like that, an update or too much installs made the games laggy, especially when using DX12.
A clean reinstall of the whole OS solved the issue, but at the cost of reconfiguring everything else
Before trying that, be sure that it’s not a problem related to the graphics card or the game files themselves by verifying the files.
After while I’ve launched game and problem came back. But I’ve noticed one thing. When I’ve changed “Adaptive Super Sampling Quality” from Quality to Balanced, it helped a lot! I don’t have lag spikes anymore.
