With triple monitors you must use GSCconfig and MultiView must be set on, which sets the config.ini variable SubViews=2 With SubViews=2 the size of objects looks pretty good but the image rendering is not really correct based on your monitor angles or eye positing. Is there a variable to set the monitor angle and also the location of the players eye heights to fix this distortion that happens at the bezel? I have done Nvidia 780ti bezel correction of course and its not a vertical shift that is the issue. Lines that cross the bezel can look bent at different angles. If there are no settings fix this, then the GSC software must assume a specific angle and eye height to get some lines straight. If you decide you want the sides of the road to look straight as it passes from the center to side monitor you can adjust the bend at the bezel if it exists moving the players eye height and/or side monitor angle to center (front) monitor angle. The side of the road straight line will bend up or down at the bezel as the head moves up or down or the angle of the monitor is changed so you adjust until its straight. Then, if the simulation distance to the object moves closer as you drive over to the side of the track then the track side line will bend at the bezel. The line will appear to bend down in the side monitor the closer it gets to you in simulation distance. So if you setup of side of the road to be straight when you in the middle of the track, as you drive inside to the apex or out to the corner exit the sight line is distorted (bend). Pictures attached. Any one have a setup solution? Rumor has it iRacing adjusts with the monitor angle as a input. I have not tried iRacing yet since I like GSC so much and there is plenty of fun to be had in GSC. I have not tried to verify how this distortion changes with changes in FOV but it will make a difference and you have to adjust your distance from the monitors, the height of your eye and the angle of the monitor to monitor and only part of the image looks perfect. Look at my examples attached, one makes one line straight with these adjustments but if look down or up on the monitors others lines are not straight as marked in red. What do the GSC author(s) assume will give the best side monitor images? Rumor has it that they picked players eye centered in monitor center and monitor angles 135 degrees? Is this documented? Got this hint: jisonga at insideRacing After recently looking into this myself I have found that as GSC 2013 is based on rFactor it has limited triple screen support. Now there is no option to set the angle of the side screens and I believe its set at a fixed angle of 45 degrees which for me was about right as I run my side screens at 50 degrees. Sidebar warning:If in the config.ini file, if you have SubView=0 for a triple monitor, the side view monitor images get very distorted, stretched horizontally by at least 2x.
