GR1 is a D3D8 game, so you'll need both d3d9.dll and d3d8.dll (the latter being something of a gateway from 8 to 9).

All is in the title , i want to find a way to have in campaign the unlocked heroes directly in first mission , instead of unlocking each as usual ,but i don't find how to do that, despite several trials  and miss  ...somebody know how to do or it's not possible ?  

Thanks for the advice ,i try the d3d9.dll from DXVK and i see effectively  a gain in picture quality and in the menus .

If you can get to it, then take a look at ghostrecon.net/forums/index.php?/topic/75165-playing-ghost-recon-1-on-modern-windows-11-24h2-25h2/. I work with DXVK which seems to solve issues that can happen at Windows 11 24H2 or newer.
