I am successfully running X-Plane 11.01 under Windows 10 with 32Gb ram, a i770K 4.2 Ghz cpu and a Geforce GTX 1080ti 11GB overclocked graphics card The 3 monitors (21:9, 34 inch 2560x1080) are identical and are set to "full screen" in a wrap around configuration (45 degrees fov left, center and right). In some locations I easily get > 40 fps but in more demanding/detailed settings (e.g., NYC), I'm lucky to sustain 20 to 21 fps with less than maxed out, even mid range, settings. Having read that X-plane is faster in 'windowed mode,' I hoped to try that option, but the choice is not available among those appearing in the graphic windows setting screen (there are only 3, not 4 ohoices), contrary to what is claimed and/or illustrated in some documents and videos explaining the graphic settings. Any insights would be helpful. Could the 'windowed" option not be available with multiple monitor setups? .
