Some advice required please

Postby Rodney » Tue Jan 16, 2018 1:12 am

For some time now I have been running P3DV4.1 with many orbx addons with great framerate results ,
the computer is made up of
Intel 4790k @ 4.4 ghz 32 gig ram , 780TI video card , SSD hard drives and latest windows 10 , I have just upgraded to a 1080TI , re formatted the computer and reinstall P3D and all the orbx , I set all the options sliders at the same as when I had 780 card.
The performance hasn't changed , P3D hasn't gained anything even with the faster card.
Just wondering could it be that my 4790K CPU is unable to keep up with the much faster 1080TI?

Just to add to my last post it seems that its not so much P3D stand alone as that has gained as a stand alone install,
Which may makes me wonder a little if the ORBX software is taking advantage of newer hardware.

If you think it has not changed anything is because you did not change anything (settings wise) , this upgrade has made the SIM react better to heavier loads , test it by upping some of the settings and see..as you said the limitation is now on the CPU..also ORBX is a passive group of files , used by P3D that is run by your system.

Yeah , the point that I was trying make out was , Identical settings in P3D with both video cards & both identical flight scenarios returned exact same frame rates and yet I would have expected a higher framerate return from the 1080TI over the 780TI which kind of makes me think P3D is more CPU reliant than GPU.

You are correct , the GPU cannot do anything if the CPU does not send it work!!!..which applies to most video intensive programs, add to this the high computation required for the flight engine..it is a matter of balance and is very hard to judge...
