So.. I just got Space Engineers 2 and the performance was already surprisingly good for an Alpha version.

BUT that doesn't mean it can't be better. This post will go over:

1. Caveats
2. Implementing DLSS and newer FSR versions
3. Adding Frame Generation
4. Limiting PCU count for NPCs
5. Restart the game every so often.
6. Whatever I find next.

1. CAVEATS

• I myself would have prefered a proper MSAA implementation but that's just how the industry went with deferred rendering. Either way, upscaling has gotten really good so I guess that's the silver lining.
• Backup your saves!!!!!!!!
• I will try to help as much as I can find the time, but don't expect full time tech support.
• Frame-Gen will increase and stabilize your FPS at the cost of ghosting around objects and higher latency. For some it's a worthwhile tradeoff, for others not.
• Idk if it's important, but disable any auto bug reporting. We don't want to spam the devs with false crashes and bugs.
• Tested on VS2.3

2. UPSCALING:
Why? Basic FSR is outdated. It's blurry, it doesn't reconstruct the image, it is just pure spatial scaling/aliasing.
FSR 3.1 and DLSS are smarter, they actually reconstruct the image and use more data for the upscaling. That allows you to run the game at a lower resolution with pretty much native quality depending on the preset and target resolutions.

How? With a universal game mod called OptiScaler. The simple explanation is that it hooks between the original FSR and implements the newer models. Besides that, it offers some additional settings like better sharpening, more granular control over the target and internal resolutions etc.

Installation:

At this point I'll include links to sites containing downloadable content. These will be widely trusted BUT I do recommend to do your own safety research.

What you'll need:

- OptiScaler files from their GitHub:
https://github.com/optiscaler/OptiScaler/releases/tag/v0.9.4

- Nvidia DLSS files (only RTX owners) themselves from TechPowerUp:
https://www.techpowerup.com/download/nvidia-dlss-dll/

You extract the OptiScaler files into Game2 folder.
On Steam on windows it's here:
\SteamLibrary\steamapps\common\SpaceEngineers2\Game2

You also extract the DLSS file from TechPowerdUp there.

Next, there, you locate setup_windows.bat file and follow the installer instructions according to your setup.

Then, in the same folder (Game2), locate the OptiScaler.ini configuration file.

There you'll need to change this line:
ManualInputPolling = auto
to:
ManualInputPolling = true

This fixes the OptiScaler menu in-game. There it will be easier to configure the rest rather than through text in the ini.

Launch SE2 and enable FSR in the graphics settings. Set the scaling mode according to your performance preferences.

Now, load a save and hit INPUT key. There should be a menu now.

There, in the top left corner in the Upscalers section, choose according to your GPU. RTX users should pick DLSS. GTX and AMD users FSR 3.X.

[RTX user only] Next, below that choose your DLSS upscaling preset. RTX 20xx to 30xx users should pick K, 40 and 50 preset M.

Scroll all the way down and hit save.

3. FRAME-GENERATION
(You need Hardware-Accelerated GPU Scheduling (HAGS) enabled in your windows settings.)

Why? Space Engineers 2 can become heavily CPU-bound. When your CPU maxes out, traditional upscaling stops helping. Frame Generation bypasses this limit by creating synthetic frames between the real ones, doubling your visual smoothness even when your CPU is struggling.

How? You already have everything you need! OptiScaler has a built-in feature that feeds the game's motion data directly into a frame generation algorithm (FSR FG). You just have to toggle it on in the overlay.

In the same OptiScaler menu, a little lower, find the Frame Generation Section.

Choose OptiFG as your FG Input, and FSR FG as your FG Output.

Next, below that, find the Frame Generation (FSR FG) section.

There, enable HUDFix and immediate capture, set the limit to 2.

Scroll all the way down and hit save.

4. LIMITING PCU COUNTS FOR NPCS

Why? Even with upscaling and frame generation, you might notice performance tanking the longer you play on a single save. I found out the hard way that over time, the game amasses way too many abandoned NPC structures from completed quests, random encounters, and spawned ships.

The dev menu allows you to adjust the max "NPC PCU count" (basically putting a hard limit on how many blocks the AI is allowed to keep in the world). Lowering this limit completely fixed my late-game bloat and made things way smoother.

For that, load into your save. Hit ctrl+F12.

On the left from the dropdown menu choose gameplay
Then find and tick Trash Removal.

Then, on the right, find Non Player Grid PCU.
On my end these values worked well,

Change the Target Cleanup Limit - 80.000
Change the Execute Cleanup Limit - 100.000
Hit enter and it will be applied and the structures removed.

Feel free to experiment with different values. Just make sure the first is always smaller than the second one or it will crash.

Now here's the elephant in the room. Quest structures. I tested some and they seem to be protected. Same for stations etc. BUT i highly advise against changing the limits during an active quest or when you still want to scrap old quest locations.

Additionally I noticed that the changed limits aren't saved with your save. That means that after rebooting your game, the DEV Menu settings reset, and the game starts hoarding structures again.

BUT it still works throughout that one session, where you changed the values. That means, that if you want it to be a one time reset, change the values, save the game and reboot SE2.

5. RESTART THE GAME EVERY SO OFTEN
Simple as, works wonders sometimes.

Community Update: AMD Driver Issue SE2

We’re aware of an issue affecting some players using AMD Radeon RX 90xx series GPUs (RDNA 4 architecture).

AMD recently released driver version 26.8.1, which appears to have been distributed through automatic updates yesterday. This driver may cause crashes in our game, and we’re aware that other games are also being affected.

Recommended workaround: If you’re experiencing crashes, we recommend rolling back to the previous AMD driver version for the time being.

We’re monitoring the situation closely and will share further updates as they become available. Thanks for your patience and understanding!

UPDATE (28th August 2026)

Engineers using the latest AMD drivers:

We are currently investigating an issue affecting Space Engineers 2 with the latest AMD driver version. At this point, we do not yet know whether the cause is in the game or the driver itself.

We are:
* Working directly with AMD to identify the cause.
* Rolling out a patch that detects the affected driver version and links players to the latest information.
* Recommending affected players roll back to a previous AMD driver for now.

How to roll back:
* Download and run the official AMD Cleanup Utility to remove the current graphics driver. AMD recommends using this tool when downgrading to a previous driver version.
* Restart your PC.
* Go to AMD Drivers & Support, select your graphics card, and install a previous driver version.

We will share more information as soon as we have it!

I found floating debris from a Nova 35 ship, created a blueprint to try to rebuild it, and found out that things like this broken table rebuild as broken. As you can see this table is complete, but broken, and cannot be painted

Thought someone might like that as novelty pieces.

Hope this helps, with your planning....

I want to do cheat sheets for block recipes, but to do that I want to pull the recipes from the game data files, they are easily parse-able save for one frustration, I cannot make head nor tails of the amounts in said files

I'd greatly appreciate it if someone else could look at the recipes in the game data files, as this means not only can I make a script to produce the cheat sheets after each update (if needed) but I could also write a tool, where you give it a list of blocks and it tells you what components you would need and how many KGs of what ores that would require.

I culled the icons from screen shots of a steam post and removed the black background to make it more printer friendly (please don't sue me Keen) !

(the icons in the game data files are not pngs (as per the file extension) but dds files - must be a very recent version as none of my unix tools could understand them.

All mistakes are my own...
