No problem; I've attached my report once more.
However I don't think I can help you guys with diagnostics anymore – I solved my problem with a full WIndows reset and update. I was working through steps with Nvidia support, and they told me to update my Windows to Build 16299.98, which apparently included a fix to DirectX. My computer would not update, and that then became the final straw.

@joaovitorpina Ah I see you have the same problem as me.
Games work first time, then afterwards stop working. Same thing happened to me with Bioshock Remastered.

@joaovitorpina Na you did your best I'm just beyond the pale :)
Also just wondering did you use DDU while on Windows 1709? I just did a full wipe and reinstall of 388.43 and no luck.

No luck chaps.
Ran DDU with a combination of driver versions and none of them worked.
@joaovitorpina the version you suggested wouldn't install for me for some reason.
Guess I'm just going to have to wait :(

Cheers man going to do it now; fingers crossed.

@joaovitorpina Thanks a lot for the recommendation, I'll check it out. Only the thing is is that I'm reluctant to use DDU because I wouldn't want to delete all my display drivers – could you possibly confirm for me that DDU works with Nvidia Optimus?

Hey Omery, congratulations in getting out of this hellhole :)

Unfortunately I've deleted the previous version so I can't rollback.

Same as OP: 1709, Windows 10 x64.

Update: just tried installing older version of Nvidia drivers, 387.92.
Error still present.

There we go second time lucky.

Troubleshooting report attached.
Had a quick look through, and this seemed notable –

Just did full reinstall of ARMA 3 – deleted all folders, cleaned APPDATA – bug still persists.
Think this is an actual bug now.

Likewise, have the same issue.
Interesting, also have the same graphics card in my laptop. Done the usual: graphics driver reinstall, verify game, etc., no luck. Does everyone else have a 630m?
