![]() Skew is caused by the C value reaching unacceptably high values, so cannot be reduced directly. In text mode the value is displayed in seconds. If it continuously rises the PC may be incapable of running the sim with the current settings. If this bar spikes occasionally it may be due to high load momentarily, or various background processes on the PC. If a user is not able to maintain a 60Hz rate they will fall behind one tick at a time. Skew is the amount of delay currently in the physics system. Lowering this will reduce the number of cars for which you are doing physics work. The physics thread runs on the CPU, so anything recommended for decreasing the R value applies here as well.Īdditionally, you may need to lower the number of cars you are receiving, using the Max Cars setting in the in-sim Options. As with the "Q" bar, a green bar is good, yellow or orange means less than ideal synchronization with the iRacing service, and it will turn red if your synchronization is dropping below an acceptable level.Ī full bar is equal to one cycle at exactly 60Hz, or roughly 0.016 seconds. The bar will turn yellow and then red as the time spent in the physics thread reaches values near the limit. If the user is not able to keep up with the physics thread the S bar will start to rise. This thread needs to be run 60 times a second to keep the user up-to-date with what is happening in the sim. ![]() The amount of time spent in the physics thread. Fixing this should be done by fixing the C bar (see below). However, if you see your C bar is also red it could cause increased packet loss (and therefor degraded network quality). Network quality is most often impacted by things outside of the iRacing simulator. In text mode the value shows the percentage of packets being received by the race server and the local machine. A value in the red for too long may lead to being dropped by the race server.Ī full bar in either direction indicates 50% packet loss. The bar will turn yellow and then red as the network quality decreases. A bar on the right indicates the server is not receiving packets from your PC. Network quality captures the number of dropped packets in both the receive and transmission sides.Ī bar on the left indicates a loss of packets coming from the server to your PC. However, if you see your C bar is also red it could cause increased latency. If none of this works there may be an issue with your ISP or another place in the network path. ![]() Latency is most often impacted by things outside of the iRacing simulator.Ĭheck for other processes using bandwidth in the background or on other systems in your network. A latency in the red area for too long may lead to being dropped by the race server. ![]() The bar will turn yellow and then red as the latency increases. Latency is the time it takes for a message to travel between your PC and the iRacing server you are connected to. HDR, Antialiasing (AA), mirrors, sharpening, heat haze, and distortion are good settings to adjust for this. Lowering or disabling settings that rely on the GPU will decrease the value. The grey value represents a short term average, while the purple bar is a longer term average. The time it takes for the graphics card to draw a frame. Shadows, cubemaps, HDR, and object detail are good settings to adjust for this. Lowering or disabling settings that rely on the CPU will decrease the value. In text mode the value is displayed in milliseconds. A second bar shows the 15-second average in purple. The time it takes for the renderer to process a frame. Solutions are also listed if you are seeing unacceptable values for a given label. The meaning of each letter is listed in a tooltip that can be seen when mousing over the value. The Graphical setting will show a bar for that setting while Numeric will show a number value.Įach row on the framerate meter shows a single letter, and then either a horizontal bar or a text value. The framerate meter can be configured to show information on a wide range of systems, and these can be enabled individually on the Options tab of the sim options menu. ![]() Pressing "F" on your keyboard will enable the framerate meter, which shows a number of performance statistics for the sim.
