Hi Zain,
It's not just the FSX/P3D sliders. There are graphics settings in FlyInside you can try setting lower, and also check your Nvidia settings and make sure things like the various AA settings are off and pre-rendered frames are set to 1. Not sure how new you are to VR but there are a fair number of places to look for optimizations.
Once you turn everything down, if you don't get the flickers any more, you can start turning things up that are important to you.
Other things to do are use task manager to see if your CPU is getting maxed out. You'll need to expand it out to where you see all the logical cores and real cores to see if one core is saturating and slowing everything down. Also, if your CPU can do hyperthreading, try turning that off in your bios. Few really need it and what it does is allow other tasks to steal time away from saturated cores. If you have CPU cores running near max, hyperthreading can hurt you.
And get/use a utility to monitor CPU temps. There have been a few reports of bad performance that has turned out to be dust-clogged heat sink/fans which then cause the CPU to throttle because of high temps. Check your GPU too. VR puts a high load on GPUs and if your fans aren't set to ramp up quick you could be having your GPU throttle.
Lastly, your computer may have other processes running. Don't know your level of experience but lots op people load up their systems with all sorts of auto notify utilities, get loaded with adware, even malware, and other junk that robs cycles from the CPU and in VR you need as many as you can get. Other things can load up the system like lots of old junk in the Windows temp directory. I always clean out anything over a week old. Windows indexing long lists of stuff in there makes systems slow to boot and just dumps performance in general.
Not sure how your CPU compares to the more current stuff but it might be a little old and slow. I might be confusing it some but just check CPU benchmarks in general and keep in mind that FSX is very demanding of CPU and will only run as fast as your CPU in most cases. To run it well you need the fastest CPU you can run.
Hope that gets you going. Flickers are just a sign that your system can't keep up so it's really just seeing what you can do to optimize everything.
