Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz
NVIDIA GeForce GTX 670 (Driver Version 355.11)
Tons of Memory
1) All set to active: Sync to VBlank, Allow Flipping, Image Settings "Mid Range Scale set to - Quality", Use Conformant Texture Clamping.
2) Override application settings: AA set to 16x, about mid range on the scale. (Similar results when using FXAA.)
3) Override application settings: Anisotropic 16x (Anisotropic at 1x had slow frame rates here! Maybe something to do with the NVIDIA Powermizer option?)
Getting around 40 FPS looking around airports and anywhere from 60-150FPS whether scenery or sea.
Only problem, VSync is active, even via command line ( $ __GL_SYNC_TO_VBLANK=1 fgfs), however FPS within flightgear is still reporting higher or greater than 60 FPS!
Overall seems better than previous versions, but likely somehow need to verify and make sure VSYNC is active by maybe browsing internal properties? Or is VSYNC to be assumed activated and just ignore FPS rates printed on screen?
(Just finished packaging for Gentoo, and compiled using standard stable O2 CFLAGS.)
I'm still seeing some graphics anomalies while looking around, or image tearing. Still leads me to believe VSYNC is not active. (If the monitor/display only has a 60 vertical refresh rate, probably wasting CPU/GPU usage rendering anything more than 60 FPS!)
CONCERNS
1) How to verify VSYNC is enabled, restricting frame rates to 60 fps
2) Frame rates seem to increase, after toggling 3D console off, and then again turning the 3D console back on. First it appears the gauges consume 10-20 FPS, but after toggling the 3D console off and noticing the increase and again toggling the 3D console active again, I can see the gauges appear to consume less frame rates than when initially taking off from the airport and flying over the open sea. Odd. Maybe something with the updating of the gauges? Then again, might be nothing and all is normal.
