Davis67: Fortunately I have Windows 10 on my newer computer, but I tried it on Windows 7 and it did not work.
I attempted the patch Kaju mentions, and it got me to the menu screen but starting any new game or the training levels ended in a crash. I was using Windows 7 x64 Ultimate, maybe there's a subtle difference with the Enterprise version 'fwoomp' (from the post Kaju mentioned) used.
Either way, like you all, I hope GoG offers an official fix.

UPDATE:
I did, after all, get this to work on Windows 7 x64... so Yay!
I can no longer find the post online Kaju mentioned, fortunately I took a screenshot the other day. (attached)
The directions mention (1) downloading helper/wrapper files for the Tomb Raider Remastered directory (2) a binary edit of the tomb123.exe program so that the function calls to kernel32.dll refer to something that actually exists.
Note: wrapper files aren't needed. Tomb Raider Remastered uses OpenGL which Windows 7 has. I just did the binary edit. I put a red X by the steps not needed (see attached). I'm using an nVidia GTX 970 with the 474.11 WHQL drivers on this computer.
STEPS:
On the Window 7 x64 computer:
(1) Install GoG Tomb Raider Remastered
(2) Install the patch
(3) Using the attached instructions, edit tomb123.exe using CFF_Explorer and follow the rest of the instructions below that step
BONUS:
If you don't use GoG galaxy, then all you may need in the root directory of 'Tomb Raider I-III Remastered' are tomb123.exe and the directories '1', '2', '3' and their contents. For gameplay screenshots you'll need to use the PRINT SCREEN key and Crtl-V to paste into Windows Paint (mspaint.exe) or use a third party application.
ALSO:
Your non-cloud save games will be stored in this folder:
%HOMEDRIVE%%HOMEPATH%\AppData\Roaming\TRX
I've also attached a screen shot of the game and my Windows version. Lara is looking at the self portrait of Jan van Eyck. Both the remastered graphics and the old style graphics run at 60fps -- I've benchmarked this (my monitor runs at 60Hz). I don't know what people are saying about the old style graphics being locked at 30fps.
Again this reflects my experience. Your mileage may vary.
1) Open tomb123.exe in CFF Explorer[ntcore.com] and click on "Import Directory" in the left pane
2) Under "Module Name", right click and select "Delete Import Descriptor" on both dxgi.dll and d3d12.dll
3) Click on "KERNEL32.dll", find "GetOverlappedResultEx" in the lower panel, double click on its name, change it to "GetOverlappedResult" and then save the file
In my case, there was no need for step 2), because references to dxgi.dll and d3d12.dll didn't exist.
However, the GOG achievements don't work even though the game runs.
