OK, XP 11.11, really rocks now.
I am using the latest nvidia drivers 390.65. and all is done done with my i5 7600K OC 4.8 ghz ang 16 gb ram at 3200 mhz, so no need for extra ram or change CPU ;-)
I am using default scenery with no addons,
XP11.11 graphic settings on both copys of XP 11 are like this.
Visual effects: High (HDR)
Textture Quality: Max (No compression)
Anti aliasing: 2*SSAA+FXAA
Number of world objects: one stop before high.
Refelction detail: all way down (cant see any reason to use it)
Draw shadow on scenery: off
allow windshield effects. off (on makes no difference in fps)
I am not using any AI aircraft yet.
I now got 30 fps smooth and stable on both instances of xp11, yeah I am really running all 3+2 monitors + one 7" with garmin 530 pop out, this i really amazing on pretty high graphics settings.
Did the following.
Open Nvidia control panel.
goto manage 3d settings
changed power managment mode to "prefer maximum performance.
( i have set the following on both XP11-1.exe + xp 11-2.exe)
open gl renderer: for XP11-1.exe (gtx 1060) and for xp 11-2.exe (gtx 1050ti)
Tripple buffering: on
Vertical sync: adaptive (half refresh rate) = 30 fps.
this did the job, great improvement in fps and lower utilisation off the CPU... wow.
Utilisation on running both xp11 installations.
CPU = 80-90%
GTX 1060 = 70- 90%
GTX 1050ti = 40-60%
this is measured in flying around and over Copenhagen in Denmark EKCH where i live.
Happy flying and many thanks to you Robert, your support was top dollar ;-)
