It's time to streamline development by dropping support for the 32-bit version of Diesel Railcar Simulator and focus on the 64-bit version only:
- Steam hardware report shows that nobody is using the 32-bit version of DRS anymore (of those players that share their hardware specs with Steam)
- 64-bit consumer CPUs were introduced some 20 years ago, so they should be commonplace
- The 32-bit version has serious performance problems owing to the max 4GB of usable RAM limit for 32-bit programs, requiring constant paging to hard drive because the game often needs more than 4GB RAM
- Some people get confused and try to use the 32-bit version even on a 64-bit system, leading to poor performance and crashes for no good reason
- Dropping 32-bit support makes development easier and faster
The last 32-bit version (the current release version) has been saved onto a separate "beta" branch in case anyone still wants to keep using it. In order to download the last 32-bit version, right-click on the game in the Steam client, choose the "Betas" tab and select "last32bit" from the list.
If you're unable to launch the 32-bit version directly from Steam after subscribing to the beta branch, try starting the 32-bit exe manually, usually located at:C:\Program Files (x86)\Steam\steamapps\common\Diesel Railcar Simulator\Diesel Railcar Simulator.exe
In future versions there will still be two exe files (one with the "64-bit" suffix and one without), but the files will otherwise be identical 64-bit executables.
