Please support WinXP! (32bit better) :P

  • set WindowsPlatform.SupportWindowsXP to true in UnrealBuildTool, and edit your project's settings to enable OpenGL shader support.
  • When running on Windows XP, OpenGL is automatically used instead of DirectX 11 for rendering

Thx for your feedback.

I look at it right now!

DONE, you can try this new version 1.5 and tell me if it's working now. ;)

Thanks a lot! Again for this kink of fix i get "not a valid 32bit app" (also on XP 64bit virtual machine), maybe it's an hardware issue but my GFX card supports OpenGL4 and the driver is updated: http://www.amd.com/en-us/products/graphics/desktop/6000/6570 ...I'll give you another feedback about the game if will be solved. Thanks again :)

Oh, I think "set WindowsPlatform.SupportWindowsXP to true in UnrealBuildTool" is something I don't know. I'm searching for a tuto or detailed steps to do it... If you find it, tell me! ;)
