So, the lower the value, the better the frame rate but also the more the blurries. The default value of it is 0.33, meaning that the CPU will spend 1 millisecond to scenery loading in every 3 milliseconds of rendering. The lower the frame rate is set, the more CPU time is devoted to loading scenery and texture.įIBER FRAME TIME FRACTION is a direct command that helps tune the amount of time per frame that CPU runs fiber jobs Performance of Flight Simulator is greatly affected by the amount of time CPU spending between foreground operation and background data scenery loading. And what it does?Īctually determines the maximum amount of time per frame that will run fiber jobs on the primary thread. Well, actually FFTF stands of the first letters of FIBER FRAME TIME FRACTION. You can use less autogen and lower terrain settings when flying to avoid blurry terrain.Įxperienced simmers know that they can use different FFTF values for maximum frames or avoiding blurries.įFTF. You can turn down your detail settings because of that detailed airport that brings down your frames. And you start again and again and again………….

You start a flight (or you just changed vehicle), you enter another area and finally frame drops and stutters appear. You are happy, you have no blurries or stutters and frames are good. Well, you can make a lot of tests until you think that you have found it. You do not want to change your settings while making a flight? You want the best value that balances between performance and image quality? You want to avoid blurry terrain and have sharpness while flying?

You want maximum framerates at detailed airports?
