Issues fixed
Technical Issues
- This game must be run under DOSBox. Being a demanding 3D game in software mode only, even modern computers have trouble running the game at acceptable frame rates. DOSBox Staging offers significantly better performace.
- Mouse movement may stop working on occasion. Save and restart the game to fix.
Bad Performance
|
Performance Fix[citation needed]
|
- Patch the game to the latest version (csmtcpip.exe).
- Download this fixed .exe file
- Replace the PS10.exe in the installation folder with the fixed version
Notes
- Without this fix the game crashes if DOSBox is set to Dynamic CPU mode. This patch fixes that issue, allowing the game to run with smoother frame rates, even at higher resolutions.
