Hi! We'll use this post for any known problems and workarounds.

If you're having a problem that isn't here, or the solution here doesn't work for you, could you fill in this form to tell us about it? Bug Report Form[docs.google.com]

That helps us fix things faster, having all the info in one place.

Thanks!

Problem: Graphical problems like missing fonts, lines or triangles across the screen, or just a blank screen
Solution: We've seen this on PCs with Intel graphics that don't have the latest drivers.
Try updating the drivers for your Intel graphics card: https://downloadcenter.intel.com/
Or if you're using a laptop with multiple GPUs, switching to your nVidia or AMD GPU should fix it.

Problem: Game won't launch, or the solution above didn't fix graphical problems
Solution: We have a new beta branch we think might help - right click Heat Signature in your Steam library, choose Properties > Betas and use the drop-down list to choose the compatibility-test beta. It should download right away, but if it doesn't you can restart Steam.

We'd love to know whether this works for you or not, so either way if you could fill in the bug form that would be great - mention you're on that beta branch, and include your hardware specs and OS version. Thanks!

Problem: Consistent stuttering or slowdown while playing, especially if your hardware is well above the listed requirements.
Solution 1: Try disconnecting any gamepads or joysticks, or wireless gamepad receivers. Some players have reported that this fixes stuttering for them
Solution 2: Adjust the SleepMargin.
- Right click Heat Signature in your Steam library, choose Properties > Local Files > Browse Local Files.
- Find the "options.ini" file and right click > Edit.
- Find the line "SleepMargin=1" and change the number to 5, 10, or 15. The correct number may depend on your particular system or what other processes you have running, but generally higher numbers will increase CPU usage.

If either of these works, it'd be helpful if you could tell us via the bug reporting form above! Thanks.
