Gtr2 is a directX9 game (like RRE) and dx9 library is not included in Win10 by default so I guess dx9 games will not work 100% if some elements are absent (missing textures or this kind of glitches)
@Durge Driven told me that nvidia profile inspector works with his AMD graphics so you can try too but it is not mandatory of course, especially if gtr2 works without it
Okay then I will download dx9 but probably leave the other alone unless I run into issues.
Do you know of a working P&G link? The one on racedepartment and most other places has a corrupt file so it won't extract correctly.
