FPS/Network Display Box ("F" key in-game)
Pressing "F" on your keyboard will enable the FPS/Network Display box, which shows your graphics performance in Frames Per Second, along with your Network connectivity detail display. The FPS/Network Display box appears in the upper right-hand corner of the screen when you're in-car and on the track:
The FPS/Network Display box shows you four values:
F (Force Feedback of the steering wheel)
The "FPS" indication at the top of the display is a numerical value that represents your frame rate in Frames Per Second (FPS), which is a reflection of your graphical performance.
The "Q" portion is a bargraph that represents your connection quality, and this bar can display varying colors -- a green bar is good, yellow or orange means less than ideal connection quality, and it will turn red if your quality is dropping below an acceptable level. When you see a red bar here, this is an indication that your connection may drop and you may be disconnected from the iRacing server.
If you are seeing a solid gray bar in the "P" meter, this means your system is incurring a lot of interrupts (or soft page faults) to manage virtual memory. You may benefit from reducing your GPU memory slider and restarting the sim. If this doesn't help try reducing your system working set memory slider. Soft page faults like these may not be that bad, but if you can get rid of them, it will surely help performance.
The "F" portion shows you if the wheel is clipping and at maximum force even though the demanded force is higher than that. The idea is keep the F so it is rarely in the red. Applies to controllers that have force feedback feature.
If you have:
CPUMeter=1 ; Include the sim-thread's CPU usage in the L/Q/S meter group?
enabled in app.ini you will get 3 more bars:
C - CPU usage for the physics thread
R - CPU usage for rendering thread
G - GPU usage (includes some driver time, we ask for how long from the driver starting a frame until driver tells us the frame has finished)
The bars are calibrated for 60fps.
