What am I missing? I have searched the forums, tried many tips and tricks to get my FS9 running smooth with the new gaming computer I have and I am very disappointed with my results. I am just wondering if anyone out there has any ideas or additional suggestions? I am running three 24" screens with triple head to go, with all my views in windowed mode. I fly in 2d panel cockpit view. Here are my computer specs: Windows 7 64 Bit, Intel i7 - 4770k cpu @ 3.50 ghz, 8g ram, Directx 11, geforce gtx 970 4g At first I thought it was because I was at an intense airport, fsdream team's lax. So I played around with settings, turned off all my ai, lowered all my autogen scenery, no shadows, all the lowest weather settings, target framerate 25. I use AA settings in the grahics card. I had the same jerky movement. Then I removed fsdream team's scenery and used the default airport, same results. Went to another default airport, yeg and still, same jerky frames. So I am still thinking it's a settings thing somewhere. Like I said, I've tried so many tips and tricks with no luck. Rebuilt my cfg, removed and added back scenery, tried the dxtfixer... Any other suggestions? I think about moving to FSX but hate the thought of all the money I paid for added scenery in FS9 and starting over, learning a new flight sim.

Until recently, I never really had any serious issues with stutters (even small ones) and only very occasionally had very brief "freezing" on my triple-screen triple-pc XP10 setup. A friend had begun having issues and mentioned them to me, and sure enough, when I looked at MY setup, I was having the same problems but on a smaller scale. Happily, after a lot of experimentation, we discovered the 'solution' and are now enjoying the butter-smooth graphics our systems were built to deliver. So I share our 'solution' for the benefit of those who may be in a similar situation. Heart and Soul of our fix is simple: ROLL DRIVERS BACK to nVidia 337.88 WHQL (Windows Hardware Quality Lab Certified driver) May 26, 2014 available here. This step is VERY important. You do NOT have to uninstall your current nVidia drivers to install this older driver. Just download the file and run it. Tech explanation: Nvidia has been optimizing for Direct X, NOT OpenGL in their most-recent driver releases, the 377.88 driver appears to be the one best-suited to OpenGL which is what drives XPlane 10. Some folks in this thread have said that the newer 9-series cards from NVidia will require a NEWER driver than this one. The nVidia website will ask you to select your gpu series, then model, and 'search' and you will be presented with a list of compatible drivers. If you're having issues as described here, try selecting the oldest COMPATIBLE WHQL driver in the list for your specific graphics card. DO NOT select a 'beta' driver. Right click on any empty spot on your desktop and then left-click on nVidia CONTROL PANEL. Click on the left side of the nVidia control panel 3-D Settings Under the GLOBAL SETTINGS tab, there is a setting "Multi-Display/mixed GPU acceleration". If you use only ONE monitor for EACH PC, select Single PC performance mode. The very next setting is Power management mode, change to Prefer Maximum Performance. Near the bottom of the Global Settings window is Vertical Refresh Rate, select Adaptive (use half refresh rate). This will lock your frames at 30fps. Even though your video card (in our case nVidia GTX 770 and nVidia Titan) is capable of much much higher rates, because we both are using triple computers to drive 3 separate monitors, the goal is to have all three screens in perfect sync with no 'break apart' of the image. Setting frames to 30 on all 3 PCs results in optimal smoothness and synchronization between all three monitors. Finally: REPEAT these steps on each PC that is driving a monitor in your xPlane setup. Please rate this post if you found it helpful. This post is aimed at nVidia 7-series (and older) owners.
