Lag spike, loading AI aircraft

Recommended Posts


I have recently reinstalled Windows 10 and subsequently P3D v4.5 and all its add-ons. I have got it running almost to the point where I am happy, maintaining a steady 30 FPS in most situations. However, I have come across periods of time in which the FPS will fluctuate heavily up and down to 10fps for a few seconds. It appears to happen when approaching larger airports. (Default and add-on). I've narrowed it down to the Ai aircraft which I am using AIG manager. When turning off AI, the lag spike no longer occurs. I've verified AIG. 

Would anyone have any other suggestions as to eliminate this lag spike? It certainly wasn't there pre reinstallation.

Thanks in advance

 Larger busier airports are going to have a lot of traffic, what you are seeing is from traffic spawning ahead approaching, departing and on the ground. The best solution is to run a traffic limiter, something like what is available in AI Companion or FSUIPC.

Thanks Dave, Im assuming this is whats causing my lag spike. I forgot to mention I am running FSUIPC limiter at 30 aircraft. However, the lag spike is still there making me believe that something with the AI is causing it.

I was curious about this. Can i have 40% AIG and limit traffic by AI companion and get a steady stutter free approach? or will i see lag spikes as the traffic tools kill and respawn AI to maintain a certain fps? 

or is it just better to land without AIG and then turn it back on once on the ground? kinda kills the immersion, but this guarantees no fps spikes.. i dont think any tool can so seamlessly turn AI on or off without a spike.. hope i'm wrong.. can others chime in on fsuipc / AI companion?
