Now you are able to play the game no problem but if you want to play it with better textures or a mod that improves gameplay download mods below:

First download this mod that upscales every single texture in the game(if you want to use this mod do not turn 32bit texture depth in setttings or the game will crash):

After you install the mod above install on top of it this one. This is a newer and better textures mod for characters in the game. Its meant to be on top of the mod above so just replace the files:

This is all for texture mods next is gameplay mod that improves stuff like enemy and allie AI, rebalances the game and many more(will break any language translation mods):

While the game looks great this great reshade can make it look even better. It was made with Bloodlines in mind but still does work great with Redemption:
