Thanks Tumppi, I had already read that thread, doesn’t tell me much tho…
To update this thread :
I managed to have video playing in N6 64 by removing Matrox wddm64_404_00_106_whql drivers and installing the xddm64_213_00_106_nowhql_se_u_w7 ones but it randomly and frequently crashes N6, even with an autosave every minute and manually saving as often as possible each time before hitting F8, this is a PITA.
N6 32 also crashes randomly but less often.
Apart from Matrox m9140 Graphic card, could there be something with UAD-2 PCIe or RME drivers/digicheck ?
Just for the record, I sent a support request on August 9th, received an answer today (19th) that’s 10 days later telling me that I checked the wrong field in my request (I checked Technical request instead of Nuendo support request - my bad). And a “sorry for the delay”…
Best regards
