GregP Posted July 15, 2024 Posted July 15, 2024 Given the popularity of the WinWing Viper MIP for use in DCS with MFDs, I'm hoping somebody may have a suggestion for how to resolve this. I found that when I enable my two DisplayLink USB monitors, it ends up disabling G-Sync on my main monitor which makes for a very stutter-y experience. Surprisingly I've found very little discussion of this online and I've only been able to locate one thread from 2012 where somebody mentioned the DL drivers being in conflict with NVCP and removing most of the latter's options (which is exactly what I see), including G-Sync. I haven't yet tried installing a new Nvidia driver set over the DL drivers, so it's possible that may rectify it, but it sounds like somehow the two different display technologies are fundamentally incompatible for a lot of advanced graphics options like G-Sync. The difference in smoothness between with and without G-Sync is huge and if I can't find a way to reenable it I'll have to give up on the DL monitors. Anyone else experienced this before and/or found a solution?
Smashy Posted July 15, 2024 Posted July 15, 2024 Not exactly your issue but posting in case it'll help in any way... I completely rebuilt my rig and added a TCL TV (144Hz, Freesync) and 3 WinWing MFDs and fought with some pretty bad stuttering for awhile. I'm no display expert but I think the problem was caused by the different refresh rates of my displays. I learned that the WW MFDs default to 60Hz with the DisplayLink software and there's no way to change that. After hours of trial and error, I found a method that got rid of that awful stutter. 1. Turn off all displays. The MFDs are connected to a USB hub that has switches for each port so this is easy. 2. Turn on TV, wait for Windows desktop to be displayed. 3. Power all 3 MFDs on. Make sure Windows recognizes all displays, then start DCS. That does the trick every time for me. I'm not at the pit r/n so I don't know if Freesync is still enabled but those horrible frametime spikes disappeared using these 3 steps so whatever. I'm also not using SimApp to manage the displays, I just manually created a multimonitor LUA instead.
GregP Posted July 15, 2024 Author Posted July 15, 2024 Interesting, thanks for posting that. My main monitor refresh rate is also 144, and I too use a powered USB hub with individual enabling buttons on each port, so your solution is worth me trying too. Although I thought I saw an option to go up to 90 Hz in the DL manager, but maybe I imagined that.
