SP Mission causes frequent performance dips

[ironk79]

I have created a SP mission and discovered a strange effect yesterday. Its a SP mission that at the start creates different missions (A-G attack or transfer) and randomly activates AI planes/airfields. I fly VR (90fps, no ASW)  and somehow flying felt not so fluid. Checked with OTT performance tool, long story short, my mission produces a frequent (about 800ms?) hard dip in fps, even just standing in the parking area. After some fiddling (turning off my OC settings) it narrowed down to my mission, since QMB missions perform good.

 

I then went in ME an just startet deleting my random switches to see if it makes a difference, or at least narrow down which "process" inside my mission was causing this.

So far I couldn't find the cause of the issue and will look into this tonight, but maybe somebody encountered something similar and can point in a direction?

OK - its not the mission, the dips also occur in QMB when starting from runway. At first the dips pulsate 1/s, while accelerating and taking off the frequency of the dips gets higher and higher,  - then maybe 20s after take off these pulses disappear, only the normal "headroom" line remains. Same when landing, dips reappear, at fist with lower frequency, higher while landing, 1hz after landing. Strange. I can rule out my OC settings, my mission, OpenComposite ( testet with steamVR too). Must be the game then. Maybe computing of the flight /rolling model, since there isa correlation between speed and the frequency of the dips.

Whatever, at least my mission isnt at fault, which is nice.
