Not sure if I should post this here or on Fallout 4 or Skyrim SE forums... but here's my issue:
After installing Skyrim SE, my 2 other Bethesda games installed on the same rig - Fallout 4 and Skyrim + Skyrim SE - all stopped recognizing my GPU and reverted to the awful default system integrated video card... and consequently reset all my games to "low" profile.
i7 CPU - 4 cores - 16Gb
Win 7 Pro Service Pack 1 - 64 bits
nVidia GeForce GTX 980 - 4Gb VRAM
Needless to say both Fallout 4 and Skyrim always ran on my nVidia card before installing SE.
But now both the RendererInfo.txt and the SkyrimPrefs.ini files point to my default video card. And my nVidia Card is not even listed in the Options of my Skyrim launcher, only the damn Intel® HD 4600.
I tried fixing that by changing the following line in SkyrimPrefs.ini:
sD3Device="Intel® HD Graphics 4600"
sD3DDevice="NVIDIA GeForce 980"
as well as change the line in the RendererInfo.txt.
I can run the game, the SkyrimPrefs.ini will keep my changes but the RendereInfo.txt always reverts back to default card - and opening the launcher again will systematically reset it ALL to default card....
And this happens on all 3 games!.. I tried to verify cache, reinstall Skyrim SE... no difference.
I can configure all 3 games in my nVidia Config panel, but since the games never use that card, it doesn't help...
This is driving me kind of nuts, ALL my recent Bethesda installs on this rig (Fallout 4 CK, Skyrim SE) have been messing up with my rig...
Just for clarification, my Skyrim SE is entirely Vanilla, my Fallout 4 is slightly modded, and my Skyrim is HEAVILY modded.
Anybody has any idea what I may try to fix this?
A thousand thanks in advance!..
