Win 7 32 bit? #16

Hi there.

Is it possible to compile your version for Win 7 32 bit?

Stupidly that's one thing I didn't check before getting excited and trying to run your fixed 3.x on my Win 7 machine! Blender 2.80 runs perfectly on it, allowing me to use my Wacom GD-1218-R 18" x 12" serial tablet on my 1070 ti.

Hope you can! Thanks!

Support for 32bit systems has been removed after 2.80 (https://developer.blender.org/D5409) along with the libraries needed to build it (as part of the build process, it downloads prebuilt libraries from their svn server: https://svn.blender.org/svnroot/bf-blender/trunk/lib/win64_vc15/). I don't know how many of these libraries still work on 32-bit Windows.

In addition to the prebuilt libraries, the minimum supported version of CUDA to build Blender 3.x is 11.1 (https://wiki.blender.org/wiki/Building_Blender/CUDA) which is 64-bit only. Because of this a 32-bit version of Blender 3.x will not have CUDA support and you will not be able to use your 1070 TI for Cycles GPU rendering. The same applies to OptiX.
