Devolver has just released a standalone Serious Sam expansion on PC, called Serious Sam Siberian Mayhem. Powered by the latest version of the Serious Engine, Serious Sam Siberian Mayhem supports both DirectX 11 and Vulkan. However, the game currently suffers from major stuttering issues on both of these APIs.
Below you can find a video in which we showcase these stuttering issues. Pay close attention to the frametime graph. As you will see, there are spikes even when you simply turn/move the camera.
Serious Sam Siberian Mayhem is a fast-paced action game and these stutters can literally destroy your gaming experience.
We’ve already informed Devolver and Croteam (the teams told us that they are currently investigating these stuttering issues). Also, and due to these issues, we’ve decided to delay our PC Performance Analysis until they are fixed.
Stay tuned for more!

A half-life 2 looking game is only getting 100 fps at 4K.. nice.
It looks bad for a 2022 game but these kind of statements are just stupid.
HL2 looks nowhere close to this…
hahahaaahha lol no hl2 doesnt have as good graphics, thats nonsense.
I don’t get it. “It suffers from major stuttering issues”, but then, we have to pay attention to the graph because it has tiny spikes in it. That doesn’t sound as major, if they are so big of an issue, then they would be noticeable at first sight, or am I nuts? Anyway I don’t notice any issue in that video, maybe my eyesight is capped at 30fps. (btw, I’m not saying it does not have issues, only that I cannot see them in that video).
You will feel them while moving the mouse. Because you can’t move the mouse in the video, you may not notice (although I can easily notice them).
Confirmed here, it’s evident throughout cutscenes to a point you can’t make out what’s being said.
Serious Sam 4 already DO these stuttering issues.
When the game first came out it was suffering stuttering issues and other perf woes, so it doesn’t sound like much has changed for the game at all.
Its sad to see nowdays so many games stuttering on modern OP hardware .
Considering this wasn’t unreal stutter engine 4 I am surprised to see any stutter on Croteam engine.
This game stuck in 90 era when it will move on no body knows
well this is unfortunate, i heard the expansion was more fun than 4. i hope they iron out the technical issues, might have to wait for a deep sale on this one.
It is more fun than Serious Sam 4 and is actually pretty good from a gameplay perspective, however, the stuttering is insane and really spoils the experience considering that this is a fast paced strafing shooter. I think Croteam’s engine is the problem. They need to fix this asap – can’t believe they released the game in this state
Between that and the save game issues it sounds like this game needs a couple months or weeks of patching and a sale to justify the purchase. Which is a shame cause it looks like a great evolution of 4.
A game that looks like it was made by a drunk person in their basement actually has technical issues too?
Shocker.
Some areas were very bad. Framerate dropped to 30fps on my RTX 3090.
I can confirm this I just got the game and it is unplaybel and I have a 3080 what the heck is going on I get about 100fps but the stutter is unbearable
