Well the Main cfg which should be located in your Documents SH5 folder.
There are resolution settings in that also.
I must say I did get your error once yesterday after installing the Speech mod and patching the game with the TDW generic patcher. But as soon as I removed both speech mods the start screen went back to normal.
My system is way under yours. hahahaha. IBM Lenovo But I use two terabyte HDD's and an Nvidia 920 as well as 5GB RAM which I want to make at least 8 for playing IL2 CLOD properly.
So I absolutely do not know why you have these problems with the game because you should not have any with your rig.
The only thing I can think of I have already explained. Mods acting out together and resolution.
But we will get there eventually and get you on the sealane.
