An interim fix for Deathloop's PC 'stuttering' issue is here

In context: Arkane's latest immersive sim-slash-shooter-slash-stealth-'em-up, Deathloop, released mere days ago to rave reviews (for the most part). As is often the case with Arkane games, Deathloop's PC version has suffered from a few nagging performance problems since its September 13 release. To be specific, some customers have been plagued by frustrating stuttering issues they can't seem to fix themselves.

Fortunately, an end to these problems could be in sight at long last, thanks to the efforts of everybody's favorite gaming graphics tech YouTube channel Digital Foundry (as well as Deathloop's developers themselves).

DF's Alex Battaglia covers all of the latest details regarding Deathloop's PC performance optimization in the video below, among other things, such as how Deathloop's PC port stacks up against its PS5 counterpart. However, the latter isn't the relevant bit for now.

What is relevant to us is why Deathloop seems to be stuttering on PC at all. As Battaglia & co discovered, it is not, generally speaking, because the game is making poor use of your system's resources. In fact, he says, Deathloop boasts fantastic frametimes, with no stand-out CPU usage problems to speak of (on average hardware, anyway). There are a couple exceptions, which he points out, but that is generally the case.

What people are reporting as stuttering, he says, is actually caused by an unusual mouse movement bug that can present itself regardless of whether you run the game at a locked 30, 60, or 120 FPS (or even if you don't lock at all and use G-Sync or FreeSync to manage hitching). When you move the camera, it occasionally stops outright for a frame -- unfortunately, that's a big enough hitch for many users, myself included, to notice and subsequently complain about.

So, what's the solution? Prior to yesterday, there wasn't one, really. However, if you're willing to delve into the oh-so-dangerous (not really) realm of hotfixes, Arkane now has a partial answer. By opting-in to Deathloop's latest beta patch (Battaglia explains how to do so at roughly the 5:38 mark above), you can eliminate the mouse jittering when running at a locked 30, 60, or 120 FPS.

Unfortunately, the issue is still present for those running on a variable refresh rate (VRR) monitor, using tech like the aforementioned G-Sync. Hopefully, Arkane will close that last little gap soon. It's evident that they're aware of the problem, at least.

So, TL;DR: how do you fix Deathloop's PC "stuttering"? Download the latest beta patch on Steam, lock your framerate to either 60 or 120 FPS (ideally) and adjust your settings as needed to ensure your machine can retain that framerate throughout gameplay. And voila, that's it! In theory, anyway.

Hopefully, DF's advice combined with Arkane's hard behind-the-scenes work will satisfy some of Deathloop's. By most accounts, it is otherwise a fantastic game.

Alright! Another game I haven't purchased to be a guinea pig for testing performance and/or stability. I love being a cheap gamer - picking up games 1+ years after they've released and are no longer selling at $50+. At least most bugs/performance issues will be resolved by the time I get the game.

The hitch on kill bug in Resi Village was certainly a cancer, but I played through the game before they fixed it and still managed to enjoy the game. I despise frame rate issues of any kind, but over the years I have rarely let them stop me from playing the games unless it was directly interfering with executing the game mechanics. All that said, I have always found such issues to be something we shouldn't have to tolerate if we meet the hardware requirements. Fixes are great, but games released fully finished and optimized are better and should be the accross the board hard standard without exception if the games are not categorically early access.

Such a brilliant game. I am not playing on a powerhouse of a PC and had sliiiight fps drops here and there. But nothing to take away the sheer fun of this game. The new fix did remove any stutter I had. A well deserved 10/10 and I already can't wait for the DLCs.

Stuttering because of mouse input? What is this original Xbox port to PC?
Unacceptable in 2021 and abysmal coding on part of developers.

I wonder if it's Denuvo again...
No, its Void Engine again....

This is not even the first time that Arkane has had this problem with this engine. It's frankly inexcusable that they would deliberately and knowingly just ignore this problem that was known about before they even started making this game in the first place

They never learn do they? (the developers)
this is why I wait a few weeks or months to buy a new game
why? then its bug fixed, has more stable performance and is cheaper
