With an i7-4770 clocked at 3.9 GHz and a GTX 750 Ti, my system was obviously not up to running P3Dv3 properly. I was running it with no air or ground traffic and various other sliders set very modestly, but still had frame rates 30-50% lower than I get in FSX. The final nail in the coffin was the disappointing anti-aliasing compared with FSX.

 

Yesterday I uninstalled P3Dv3, until such time as I can upgrade to a much more capable computer.

 

 

 

 

I still have an i7-2600, 3,4 GHz, not overclocked, plus a GTX 760, and will probably keep it over the next year, maybe just replace the graphics adapter by a 970. Prepar3d3 runs pretty well with very (too) high settings, with the possible exception of a few well-known singular areas like ORBX SF Bay or Seattle where frame rates drop below 20.

 

At present running without NI, there isn't much shimmering left on the 3440x1440 screen.

 

Kind regards, Michael

That really is not a bad PC - it's more a case of...what are your expectations from the spec you have? I'm running the same processor, with 8GB RAM but i do have a 970gtx card with 4gb memory. My performance is fairly stable and not bad at all.

I found that by far the best solution to the persistent AA issues is a 4K monitor. I have not been bothered about AA at all since upgrading to 4K

Which is a big step up from my GTX 750 Ti card with 2GB.

Agree

I have most of the sliders on the first page rammed to the right (apart from LOD Radius @ Ultra and Tesselation Factor @ High), and then keep my fingers crossed.
