Check the patch before copying launch-day advice
For a Geoplanetical low FPS fix, start with the game's current update status. The October 28–29 official notes identify specific performance problems that received fixes. Those notes are a better starting point than assuming every slow menu, hot GPU or simulation pause has one cause.
The October 28 release patch reports a laptop issue where the game used integrated graphics instead of the dedicated GPU. It also reports a correction to the frame-rate limit on the menu and country-selection screens.
Recognize the version 1.0.2 V-Sync fix
The October 29 1.0.2 announcement reports a fix for stuttering and overheating with V-Sync turned off. Check whether that update is installed before applying advice written for an earlier build.
This identifies a patched condition. It does not establish that switching V-Sync in either direction is a universal FPS improvement, or that all remaining stutter comes from the same bug.
An earlier October 29 stability announcement also describes smoother loading, especially on lower-memory PCs. Loading improvements and a frame-rate fix are different claims, so do not treat one announcement as a measured FPS result for every system.
Review the graphics controls that exist
The official gameplay FAQ documents a graphics preset, texture quality, render resolution and frame-rate limit, plus fullscreen and windowed modes. Use those actual controls when checking performance.
Compare one setting at a time in the same scene or menu so the result is easier to interpret. Keep a note of the starting configuration and whether the symptom is low frame rate, stutter, loading delay or an unresponsive menu. This is a troubleshooting method, not a claim that a particular preset has been tested on your hardware.
On a laptop with a dedicated GPU, verify which adapter is being used rather than assuming the older integrated-GPU bug still describes the installed build.
Report what remains reproducible
If the issue persists after checking updates and the available settings, record the game version, hardware, graphics configuration and the screen or action that reproduces it. Include whether the slowdown occurs in the menu, country selection or an active campaign.
Use the official Steam community and patch announcements to compare known fixes with the exact symptom. A patch note reports a developer change; it is not a benchmark or a guarantee that every player's issue is resolved.
FAQ
Is there an official fix for V-Sync-off stuttering?
Yes. The October 29 version 1.0.2 notes explicitly report that fix, along with overheating in that condition.
Why should laptop users check the GPU?
The October 28 patch reports fixing a case where laptops used integrated graphics rather than the dedicated GPU.
Will lowering graphics settings fix every slowdown?
That is not established. Distinguish rendering performance, stutter and loading or simulation delays, then report the actual result of a controlled change.
