UI is Slow

File:Titans-icon.png In-game UI is Slow

Build menus for fabricators, factories and commanders take seconds to appear and generally feels laggy.

File:Gold-rank-icon.png Check Minimum System Requirements

Some systems are under powered and may struggle even if they meet the minimum system requirements.

File:Gold-rank-icon.png Out of Date Drivers

Make sure your drivers are up to date.

If you have a dual GPU system with switchable graphics check that both your high performance dedicated GPU and integrated Intel GPU are using the latest drivers.

Coherent UI will often default to the integrated Intel GPU.

Check the BIOS for any option to increase the allocated VRAM (video ram).

Intel HD Graphics Black Screen or Slow Load

File:Gold-rank-icon.png Select the High Performance GPU with Switchable Graphics

If you have a dual GPU system with switchable graphics using an under powered integrated Intel GPU then check that both Planetary Annihilation and Coherent UI are using your high performance dedicated GPU with latest drivers.

Test with your firewall / antivirus disabled then add exceptions for both Planetary Annihilation, CoherentUI and the server to prevent real time scanning.

Test Windows Compatibility Options

If you have any full screen display or high DPI issues then test the following:

• Windows Compatibility Options: https://support.microsoft.com/en-nz/help/15078/windows-make-older-programs-compatible
  • Disable display scaling on high DPI settings (Windows 7 / 8.x) / Override high DPI display scaling behavior: Application scaling (Windows 10)
  • Compatibility mode: Windows 7 or Windows 8
  • Disable fullscreen optimisations (Windows 10)
• Game Mode: https://support.microsoft.com/en-ie/help/4028293/windows-using-game-mode-on-your-pc

File:Gold-rank-icon.png Reducing Coherent Processes

For under powered systems you can limit the number of Coherent UI rendering processes using the --coherent-options="--renderer-process-limit=16" command line parameter (launch options in steam).

Try a few different numbers less than 16 to optimize for your computer. eg 8

If that doesn't help try the command line parameter --software-ui as a last resort.
