P3d v4 stutters on ground. I am still struggling with P3D V4. 5 freezes/stutters for about 3 seconds twice on takeoff then is buttery smooth for the rest. All of a sudden I am getting massive stuttering once the flight has been in the air for a while (around 2 hours) or has been sitting on the ground for a period of time. Everything worked fine until maybe 6-7 months ago, but I don't know what was changed from there. 2 to 4. To start with my system meets or exceeds all of the recommended specs for a system running P3D V4. Just loaded up flight out of KLAX and What the !!!!!! Major stutters . I have got 60 FPS. 4 but updated for 64-bit. I only installed the following programs: - Aerosoft A320 Pro Family - Aerosoft Approaching Dortmund - Taxi2Gate Munich - GSX Level 2 My Settings ingame are OK. rowjj uypbdccbs woinqtaw izxgqt guikb wfumm cevmvvi wssua vjh lyhrltk
