Thanks. From what I’ve seen there is no major difference (at the moment) between the two cards.
When initially playing DCS I had a jitter/stutter - not seen before in my earlier days. Lots of internet searching - with helpful and not so helpful bits of advice - most of it out of date - so embarked on my own troubleshooting. Lots of messing around with Nvidia CP settings, and in game settings - nothing working - sometimes getting better, sometimes worse.
Reset Nvidia CP settings to stock and installed MSI Dragon Center - which gave me the option to selecting ‘User Scenario’ pre-sets. Opted for extreme, flew and no jitters whatsoever. Uninstalled it (hate manufactures ‘One Solution software’) and pressed on. No jitters and all settings on Max.
Then began thinking what changes did the MSI install actually do, as it also installed a Ryzen SDK and something called cFos (LAN ‘optimiser’ - more on that below). When I looked at my power options they were now set to ‘Ultimate’ - which sets Link State Power Management to Off, and Min/Max CPU power management to 100%.
Re-installed MSI, and selected MSI back to balanced - jitters. Re-set it to extreme, Nothing. So - to cut a long story short and a lot of installing/uninstalling and testing, uninstalled MSI DC with it being set to Balanced, which in turn reset Windows power options. Rebooted, ran DCS to confirm stutters, and then set Windows Advanced Power Options back to High Performance, as this selects Link State Power Management to Off, and Min/Max CPU power management to 100%. Now have a rock solid performance with no jitters/stuttering at all.
Now - cFos is a ‘LAN Optimiser’ by all accounts. In my experience it kills an internet connection speed - my upload going from 30 mb/s to 5, and making the download speed very unstable.
Hope the above is of help to someone?
