Yeah I think so. I had a chance to try it a bit before the beta suddenly arrived, and didn’t have any performance improvement. In the beta though, I see a huge improvement with DX12.
It’s a pity with the simconnect issues though, even though default AI traffic is slightly better. From FSLTL:
And:
If you are using beta SU11 - please do not start raising support queries about why aircraft are not at the right altitude, going the wrong way, not landing… we have only just go access to this beta too - Asobo appears to have broken many things with respect to simconnect injected traffic. If you can reproduce your problem on stable SU10 - raise a support ticket - otherwise there is nothing we can do at this stage while we test and try and get answers.
