Making OMSI 2 Run Faster Tutorial

Welcome to the Making OMSI 2 Run Faster Tutorial! Here we'll show you a few tricks to improve the speed of game loading and playability, and give you options that will suit your play style. We won't be talking about graphic settings or frame rates, just the options we've played with in the past to improve the feel of the game. If you're struggling with low FPS, you should play around with your graphics settings to get the best out of your game. For example, turning off shadows and stencil buffer effects, adjusting the map complexity etc.


OMSI 2 is arguably the best bus simulator available today. That doesn't mean it runs like the best, sometimes it feels pretty laggy especially on older hardware. As you improve your PC you'll inevitably notice some differences and some minor improvements, but if you're willing to sacrifice some features, maybe you'll find it runs even faster and smoother.

Idea 1: Disabling AI Buses

Disabling AI buses simply means no AI buses will be spawned. You and you alone will be tasked with transporting every passenger in the town or city of your choosing. This is a great option if you have a lower spec PC, and you can definitely play with some of the other options too such as reducing the AI list or adjusting the priority of schedules. Turning down the amount of vehicles on the road could also give you a small boost. You should tweak these settings to see which work best for you.

Idea 2: Disabling/Enabling Some Advanced Options

The "Advanced" options tab has a few things you should take a look at. Firstly, we have Autosave. Whenever you stop your bus, at a bus stop or a set of traffic lights, the game will Autosave! Do you really need this feature? If you're half way through a long journey, you can always manually save your game. Autosave can and most likely will cause a short freeze as it saves the data from your session, we think this is a no brainer and you should turn this feature off.

The second set of options you should take a look at are the Collisions options. You may notice that some larger maps even tell you to turn these features off as they just require a few more calculations from the game engine to work. Disabling collisions between the vehicle and terrain won't prevent you from bumping up curbs or enjoying the rumble of the road, it'll just prevent you from crashing into buildings and lamp posts. Disabling collisions between user vehicles and pedestrians is, in our opinion, another no brainer. Unless you're challenging yourself to park in a tight spot or test out your yard driving skills, there's no need to have this enabled. Furthermore, hitting pedestrians is something you should be avoiding anyway but on the off chance one of them decides to walk out in-front of you, it'll prevent that annoying pop-up that pauses your game. Disabling collisions Between AI vehicles will prevent the sometimes idiotic AI from side swiping your bus and upsetting your passengers. This is especially good on extremely tight maps.

Finally, check out the performance option titled Load whole map at start. Now this is a personal preference you'll have to make. If you're running on a fast SSD and you have a decent computer, the performance impact could be negligible here. Enabling this option allows the map to load every tile before you even load into the game. This means that as you're driving along at the speed of light, you will notice less of the little pauses as new map tiles are loaded into the world. The option does state that it does require more RAM to work, meaning a huge map will take up significantly more RAM to load.
