Well, I found a solution to the problem. If I start the game with "Load Custom Textures" enabled, it won't load properly. If I however tick the box while the game is running it renders completely. It looks so pretty :3 Really long loading times though but I'm not complaining. It runs at 30 FPS with small lag spikes now and then.
If anyone has problems with the mini-map not functioning I found a solution to that as well. If you change the "EFB Copies" to "RAM" when the HD textures aren't loaded, and then change back to "Texture" and then load the HD textures the mini-map will function pretty good.
I tried using D3D11 but the HD textures looks like a complete mess. Not sure why that happens.
