The HQ patch is ultimately the easiest way and safest way to do it i think plus it comes with a ton of upgrades and bug fixes though it will break alt tab the easiest way to fix it is to copy the d3d9.dll file from AMS if you have that game and replace it with that or rename the gtr2mapplugin.dll file to d3d9.dll.
Not necessary.
The gtr2.exe's are different versions.
In fact there are at least 5 different gtr2.exe's and at least 3 that do not require a a disc in the driver or mount a iso.
The Steam gtr2.exe got some drawbacks but there are a lot of things is does much better than the other two. So if the OP wants to use the version from steam then it is pointless to download the one in the anniversary pack!
The .exe's has nothing to do with the other upgrades.
And if XD are important then there is another gtr2.exe then the one in that archive that in general runs better!
Again just in my opinion! And Paul do not agree!
WITH STEAM YOU MUST COPY GTR2 GAME OUTSIDE STEAMAPPS FOLDER BECAUSE STEAM WILL RESTORE DEFAULT EXE AND DELETE ALL UPDATES/MODS
It is a very good idea to do that but Steam will not overwrite anything in the gtr2 folder unless they make an update (fat chance) or you ask Stream to verify the files for gtr2.
And even that will not delete anything!
RIGHT MOUSE CLICK ON EVERY EXE TO SET ADMINISTRATOR+WINXPSP3 COMPAGIBILITY
On Win 10 that is not a good idea!
No need to set compatibility for any of the gtr2.exe on Win 10 since +2 years it just slows down the fps and prevent some features to be used.
Even Admin right can course issues with external programs! I do it as I like the convenience of having the .plr file in the local UserData folder.
oh no look what you have done op you have unleashed the mod creators wrath/s
Paul is just tired of spending a lot of time writing very long and detailed install and setup texts that few bothers to read
Have send him both so water under the bridge!
