Hello everyone today in microsoft flight simulator 2020 we will discuss another performance tweak that can help reduce lag , stutters and increase fps. Please keep in mind that not all systems are the same and the results will vary that said these 3 steps should make your sim smoother and hopefully less stutters. In the video i go over the hpet in windows and why it may benefit you to turn this off i also go over how to do that as well. Next we will revisit the islc program that many of you may be familiar with from the last video But there is 1 thing that we did not do and that is to optimize the the timer resolution . In this video i will go over how to achieve the .5ms response time to get the best latency possible with the least amount of lag. If your timer res. is lower that .5 on not exactly .5 then you need to follow these steps to correct this. Lastly we go over the nvidia resizable bar and what it is. Turning this on will warrant a 5 to 10 percent increase in fps. The only down side is that this is only good for 30 series gpu and some amd. The up side for and users is that you can expect a bigger increase in performance when you turn this on. Msfs is not set up for resizable bar by default so this method will force the function in the sim.  Below is the copy and paste section as well as how to revert from hpet off to hpet back on if you so desire. If you have any questions please post them below and don't forget to like share and sub to the channel!

In the nvidia inspector to revert the 3 lines back to normal to the right of the drop down next to each line you will see a little restore button click that to revert to default for each line . then hit apply at the top.
