Hi Spud,
Yeah, I have no idea about P3D and I am kind of stuck in my ways, in the way of staying FSX. But I promise you... If you are just using FSX with the DX10 fix and Add-on converter X for older aircraft, then DX10 with the fix is problem free.
But more than that. The performance gain is so dramatic, you will never go back. It will allow you to push up your scenery sliders at a minimum of 25% with no frame drop. More than likly a frame gain. I run at a constant 30 FPS only dropping to 15 FPS in major cities.
The graphics gain will also be extreme. I will be releasing a Misty video very soon and you will see what I mean.
My FSX experience is lag and stutter free 99% of the time. That 1% happens in large cities and only when cloud cover is dense. Keep in mind
ALL my graphic sliders are set to max.
I get where you are coming from, believe you me. But this is one of those things you really should not be missing out on..especially if you love FSX.
Happy New Year Spud!
