I have a NVIDIA card, windows 10, on a very good PC.

I can play the game just fine for 5 mins, but after that the game crashes (it freezes). If I restart the PC and load the oldest save file the game works just fine again, for about 5 mins and then crashes again.

I have the feeling that if the game has to load new cells it gets worse (and crashes sooner).

I tried to google it, but I have mostly only found "Games for windows live" and Intel graphics card bugs.
My problem seems to be memory related.

Any help and comments welcome.

Did you have a integrated graphics card? if yes, i suggest you go in the "nexusmods" and search for "Intel HD graphics Bypass package" and download the d3d9.dll

Thanks for the reply.
No I don't, as I said in the above post, in the first sentence, I have an NVIDIA Card in a very good PC.

Nonetheless I tried it already and it didn't work.
