Een terugkerende vraag blijft ook wat de diverse meters in het FPS scherm betekenen. Hieronder de engelstalige
uitleg geplaatst door Randy Cassidy op het iRacing Forum:
L - Latency
The number of milliseconds it takes for data to make the round-trip from your computer to the server and back.
Q - Quality
The percentage of network packets that successfully make it from the server to you (or vice versa).
S - Skew
Measures how well your computer is keeping up with the server. A small amount of skew is not uncommon, and is caused by variations in Latency. Significant skew is virtually always an indication that you computer is falling behind the server. That is, it is taking your computer more than 1 second's worth of time to run the simulation forwards 1 second in time. Your computer thus "falls behind" the server, leading to skew between where, in time, your simulation is showing the simulated world vs. the server (and thus everyone else in the server that is not also suffering from skew).
To enable the meters below, edit My Documents\iRacing\app.ini, and in the section at the bottom change "CPUMeter=0" to "CPUMeter=1".
P - Paging
How much does the computer have to swap memory into the sim, away from other programs. The gray bar measures all page faults (both those that need to read from disk, and those that don't), while the colored bar measures page faults that require going to disk. See
MSDN: Memory Object - gray = "Page faults/sec", colored = "Page reads/sec". Much of a colored bar means that either the sim is using too much memory (graphics and/or system memory sliders set too high), or that other programs on the computer are using memory and taking it away from the sim.
C - CPU
How much of the available 1/60th of a second of wall-clock time did the sim take to advance the simulation by 1/60th of a second. Or, how close is the sim to falling behind the server, leading to Skew.
R - Renderer
Measures how much time it took our renderer to queue up the frame for the graphics card.
G - GPU
Measures how much time the driver it took the GPU to render the frame.
