I'm also getting the Link reset issue now, but just about everytime its been associated with the loading phase of a mission. I haven't had any issues in play. I suspect it might have something to do with the new hand-tracking feature in the software. I disabled hand controllers in DCS a while ago so I bet doing that might prevent issues in play for others, but i'm unsure.
Good and bad news for my F-14 VR issues. The bad news is that the SSD did not fix the stutter/lag on F-14 or Syria. The good news is using both lxssapper's and Wazowsky's texture mods I did fix F-14 and can run DCS at high textures now. It would've been a bit of wasted money, but in fact I needed more storage space for this computer anyway so it's no big deal.
As for Syria, still getting bad performance at texture settings-high. It looks fine on low settings anyway but it might be time to look into a VR textures mod for it too.
