When I revert to FSX+SP1 only, I have no problems and Track IR Pro is very stable and runs perfectly. (No jagged/ripple occurs when your head is stationary) Both Photo and standard FSX distant scenery seen beyond the cockpit frame is also affected, but not so noticeable. Service Pack 2 brings computers running Flight Simulator X or Flight Simulator X Service Pack 1 into multiplayer compatibility with Flight Simulator X: Acceleration. The jagged/ripple is very noticeable on the VC cockpit vertical glass frames when panning with Track IR Pro. I have Nvidia's latest 8800 GTX Driver (169.25) and have also tried the previous two driver versions. I have also tested with DX10 disabled by unchecking the DX10 box in FSX but the problem is still there.

Your Flight Simulator X installation must have all original files unchanged: a repair may be necessary if you have changed any files. It detects Standard versus Deluxe SKUs and installs appropriately. The service pack is one download per supported language.
FSX ACCELERATION PACK SP2 INSTALL
As you know, the DX10 options box within FSX is automatically enabled when you install FSX Acceleration/SP2 if you have a DX10 Graphics card. Download the service pack to the existing Flight Simulator X installation.

Install the SDK SP1A from there using fsxsdksp1a.exe, (dated, size 165,569KB). Acceleration also contains a version of SP2, lets call it SP2-builtin. It will install SP1 if you have not already done so. Acceleration installs on top of RTM and SP1. SP1 and SP2 ( lets call it SP2-standalone ) are service packs.

Browse to the subfolder called SDK\SP1a\. FSX-specific: Acceleration is an expansion pack to RTM.
