How To Fix Unable to Launch Problem in Serious Sam: Siberian Mayhem

About the game

Here you will go back to the world of Serious Sam in ‘Siberian Mayhem’ – a new standalone chapter in the adventures of ‘Serious’ Sam Stone.

You have to make your way through the vast Russian landscapes on a quest to catch up with the traitorous General Brand, who remains one step ahead of Sam at every turn. The road is long, and there is oh so much to see.

Co-developed by Timelock Studio and Croteam, ‘Serious Sam: Siberian Mayhem’ presents an expanded look at a familiar journey full of forgotten stories, unexplored places, and Sam’s trademark guns-blazing battles against Mental’s Horde. So go ahead and join the fight, comrade!


The game welcomes you to Siberia…the heart of Russia. This place is huge, cold, and so unpredictable even the alien invaders feel lost.

You can travel through five new levels set in a beautiful and dangerous world, from Arctic coastlines and desolate forests to abandoned villages and a chilling ghost town. Siberia is large enough for you to fight & explore for as much as you want.


Only the strongest souls survive in Siberia, and Mental knows it well. A new set of dangerous foes and bosses join the Horde in ‘Siberian Mayhem’. Including some of the most advanced and intimidating creatures you never expected to see.


There’s only one thing that stands between Serious Sam and his enemies – a gun. You get to treat yourself with a deadly arsenal of new weapons, from the legendary AK to experimental ‘Perun’ crossbow, and more.

Do you want to cause death from above or become one with 50 tons of first-class firepower? New gadgets and vehicles here are locked, loaded, and ready to fulfill your most destructive dreams.


When you think the journey is over and there are no more stories to tell, the universe gives you a second chance. You will meet a gang of new outcasts and unexpected characters who will help Sam on his journey to Tunguska.

In this game you must complete side-missions in order to uncover new chronicles these wild places uphold. And you need to pay attention to your surroundings – the world itself can tell you something you never expected to hear.


The lands of Siberia are huge, desolate, and full of secrets. Useful, silly, weird, familiar… you name it, its a mixed bunch. You will get a chance find out all its secrets.

How To Fix Game Crashing Problem

If you happen to have an old GPU, you might be having trouble launching the game. You’re maybe getting a disclaimer saying your PC does not match the minimum requirements to run the game.

You select yes and you are greeted with a grey/black screen. Shortly after, the game crashes with a crash reporter. If this is happening to you then I have a fix that MIGHT possibly work.


You need to right click on Serious Sam Siberian Mayhem icon on the desktop or wherever you have it saved. Then go to Properties. From there in the General tab, you’ll find a Launch options area. Add the following code in the launch option section:

+gfx_strAPI D3D12

if this doesn’t work, then:

+gfx_strAPI Vulkan

For me, the first command worked, but only after trying to use it for the second time. So if one doesn’t work the first time around, try the other one, then come back to the first one again. Hope this works for you.

At the lowest settings, SS: SM works well. It is playable on the lowest settings at 1024 x 768. Just make sure you’re on the lowest settings for the graphics and Prebaked Lightings is enabled. Take note to not change the API settings inside the game also.

I really hope that my fix works out for you. Leave a comment to let me know your feedback. You can follow us on Twitter and drop a like on Facebook to get the latest update on guides for Mobile Games, PC Games, Fixes, and Settings.
