VMWare & Software render - updates

In case there are others running OpenSCAD in VMWare VMs.

I'm running VMWare Workstation Player 14, hosted on Windows 7-64.
It runs a VM of my previous metal based Windows 7-64 desktop system, as the
metal was dying.
From a Debian system I access the VM via FreeRDP.
I did that a couple of years ago, intending to migrate functions to Debian.
(tardily)

To get OpenSCAD working on the VM, I had to implement S/W based rendering,
using an OpenGL DLL.
Without it I got a capability warning, as it only supported OpenGL 1.??.

Recently Windows Update, in the VM, offered up an Optional Update, VMware,
Inc. - Display - 8.17.2.14.

tl;dr
After installing it I no longer need the DLL. It's still S/W render, but
built in the driver.
Help/Library-info shows
OpenGL Version: 3.1 Mesa 20.2.0-devel (git-bced9b46e7)
GL Renderer: llvmpipe (LLVM 5.0, 256 bits)
GL Vendor: VMware, Inc.

Longer story.
I was having memory leeks on the host which looked like they were from the
VM.
So I looked for a VMWare update.
v16 said 'Support for DirectX 11 and OpenGL 4.1 in the Guest' - oh good.
However they dropped support for Windows 7 - oh not good.

So if you have Windows 8+ you can get built in OpenGL 4 support in VMs.

That was why, after the driver update, I tested OpenSCAD without the DLL.
And it works. So far.
I'll see if performance has changed.

I note Workstation Player 15.5 is the last to support Windows 7 (SP1) as
host,
I may give that a go. Sometime.


OpenSCAD Admin - email* me if you need anything,  or if I've done something stupid...

Well that didn't take long, performance is crap with a complex models,
unusable.
Looks like I'll use the DLL again. Then see if 15.5 does anything better...
