Veedub looks like Microsoft have made some improvements on Windows 10 game compatibility.

Further good news, when running the game on Windows 10 with DDrawCompat, the game is now a near perfect out-of-the-box experience! Well at least that is the case on my Core i5 4570 desktop with Intel 4600 and single monitor.

Windows 10 without DDrawCompat ~60 FPS in menus and ~20 FPS in races (too slow)
Windows 10 with DDrawCompat ~60 FPS in menus and ~30 FPS in races (perfect)

I wonder if the frame rate in the menus is being restricted to 60 FPS by the Windows 10 OS (e.g. 59Hz refresh rate or Vsync rates etc.) as usually its unlimited FPS in the menus. But clearly DDrawCompat makes a difference to the 3d race engine and the game is running at perfect speed. Mouse clicks are now normal again but accelerated time is back to its slower/normal acceleration (for you DxWnd/VirtualBox users following the other thread).

So to run through the installation steps once more for Windows 10 users:

  • Four year old Core i5 4570 with Onboard Intel 4600 GPU
  • Fresh install of Windows 10 Pro 64-bit version 1803
  • Copy gpw folder from CD to C:\
  • Create a folder called "Save" inside your GPW folder (C:\gpw\Save)
  • Download the latest release (currently v0.2.1) of DDrawCompat
  • Copy the ddraw.dll file to your GPW folder (C:\gpw)
  • Download and run GPWEdit v1.0
  • If prompted, select your GPW folder (C:\gpw)
  • Click the upgrade game button and click on the Upgrade button
  • Close GPW Edit
  • Run gpw.exe and accept the installation of DirectPlay
  • Game should load successfully in full screen (although not fully stretched)
  • In the options set the race speed to 150% and enjoy

This game now has a past and a future! :1cheesy:
