Move closer to your screens - if your using a desk and the limiting factor is pedal distance then move your desk away from the wall a few inches. This will keep your pedal distance the same but you will be closer to your monitors. Move your screens closer to you - your screens need to be as close to your wheel as possible Upgrade to bigger screens - 27" is best bang for your buck and look for 1-5ms response time and 144hz if your GPU can push that.

To use ROOT TH1::SetDirectory, you first need to create a ROOT TFile object that represents the output file. Then, you can call the SetDirectory function with the TFile object as the argument. This will set the output directory for any histograms created after this call.

Now we will adjust the driver head rotation (Orient P). Use this same halved number and multiply it by 0.3, this will give you the driver head rotation number. This will align the monitors to the original number that made your monitors straight, but also keep the driver's eye line to the horizon.

If you don't use ROOT TH1::SetDirectory, histograms will be saved in the default output directory. This is usually the same directory as the script being executed. However, it is recommended to use SetDirectory to specify a different output directory for better organization and management of your histograms.

My best tip is to jump in a car and open up the camera tools (CTRL F12). Adjust the Vanish Y, until everything across all monitors looks straight. Once you have a number that works, set only half of that number to Vanish Y.

Yes, you can call the ROOT TH1::SetDirectory function multiple times in one script. Each call will change the output directory for any histograms created after that call. However, it is important to note that the last call to SetDirectory will be the one that is used for all histograms.

No, calling the ROOT TH1::SetDirectory function will only affect histograms created after the call. Any previously created histograms will remain in their original output directory.

Calculate FOVfrom focal length

Once you have the above set in iRacing correctly and you have made sure your monitor angles match the above angle, you now need to make sure your horizon is set correctly, based on your height against your monitors. This will prevent warping on your side monitors.

The ROOT TH1::SetDirectory function allows you to set the output directory for histograms created in ROOT. This means that any histograms created with this function will be saved in the specified directory instead of the default directory.

This Field of View (FOV) calculator will help you setup your screens for sim racing, giving you a correct feel within the sim that will help you become faster and more consistent.
