Quest 2 & Microsoft Flight Simulator Stuttering Performance Problem

Every time i would put on the Quest 2 VR headset in game and in the Oculus home screen would lag down to 8fps.

It would do this every time i put on the headset when it was linked up via a USB 3.0 cable.  The headset had no problems with any other game and the game ran fine when in non VR mode.  The PC was Windows 10 fully updated with drivers and updates.

So i tried everything i could think of to fix this problem and it was alot.

  • Latest BETA Oculus Software
  • Latest BETA Graphics Card Drivers
  • Uninstall & Reinstall of Graphics cards with clean install and DDU
  • Lowering graphics settings in game
  • Windows 11
  • Complete Reinstall of Windows 10
  • Oculus Tray Tool
  • Power Plan settings

The reinstall:
This was where most PC problems get resolved and at first when i booted the game up up with a brand new Windows 10 install the game ran fine in VR.

Then i thought the problem was fixed so as i began reinstalling software like Steam,Visual Studio,Visual Code,Bit defender.  The problem unexpectedly started happening again which was incredibly frustrating to say the least.

then i had an Eureka moment, the problem seemed to come back when i reinstalled Bit-defender.  So i thought it must be interfering  somehow with the game?

Exclusions:
I then fired up the Bit defender settings and added the folder where the game is installed to the Exclusion list of Bit defender.

MSFS main folder added as an exclusion in bitdefender.

 

 

 

 

 

 

 

 

After trying the game again with the new settings in Bit defender, the stuttering and loss of fps went away!

Windows 10 Wont enter sleep mode with Logitech Extreme 3D Pro Joystick plugged in

 

 

 

 

 

 


Windows 10 Wont enter sleep mode with Logitech Extreme 3D Pro Joystick plugged in.

I ran into this problem a while back as no matter what i did my PC would enter sleep mode.  i tried everything;

  • bios settings
  • windows power saver settings
  • driver updates

Turns out it was due to having the Logitech Extreme 3D Pro Joystick plugged in which i might add is a superb Joystick for Flight Simulator 2020.

Geforce Experience Bug:

Turned out, there is a bug in nVIDIA experience, down in the Windows driver level that would prevent the system from being idle, if you have a joystick plugged in (the article goes a bit deeper into details, it is very interesting if you are a software development related kind of person).

TL:DR , if you have nVIDIA GPU + nVIDIA GeForce Experience installed + have any kind of joystick plugged into the system , Windows won’t be able to sleep/turn screen off automatically until either:

  1. You turn off nVIDIA GeForce Experience in-game overlay.

  2. You unplug ALL joysticks off your system.

PSA: if GeForce Experience is enabled and joysticks are plugged in, Windows can’t automatically turn off screen / go to sleep. This is critical if you are using an OLED screen for your simpit.

create your own search engine using searxng and linux

The excellent network chuck on youtube made a video the other day about making your own search engine with searxng so i thought id put the steps involved on doing in locally in Linux.

Update our linux installation

sudo apt update && sudo apt upgrade

install docker;

sudo apt install docker.io

install docker compose tool:

sudo apt install docker-compose

navigate to dir where you want to keep searxng, in this example well put it in “/usr/local/”

cd /usr/local

download searxng;

git clone https://github.com/searxng/searxng-docker.git
cd searxng-docker

create secret key;

sudo sed -i "s|ultrasecretkey|$(openssl rand -hex 32)|g" searxng/settings.yml

start up docker containers

sudo docker-compose up

point your browser to;

localhost:8080

Tweaks and settings;

See here for how to change things;

Fix performance problems with Virtualbox and Vmware on Windows 10

If Virtualbox & VmWare is causing massive problems with just getting a Virtual machine running in windows 10 its probably because you have Hyper-V enabled.  I learned the hard way that having Hyper-V enabled and running Virtualbox is a nightmare.  I kept getting the error;

MP-BIOS bug: 8254 timer not connected to IO-APIC

Disable Hyper-V if its enabled in windows 10 by going to “Turn windows features on or off” and un select “Hyper-V”.

 

 

 

 

 

 

 

 

Also make sure that its disabled in bcdedit by making sure that you run the command;

bcdedit /set hypervisorlaunchtype off

Reboot your System and Virtualbox and Vmware will now work much better.

How to remove the Bitdefender context menu from Windows 10

Bitdefender is a great piece of software with a huge range of security features but doesnt give an option to remove the annoying menu option that pops up when you right click on a file., of course there is a way to remove it.

Download a program that makes this easy called “ShellxView” from https://www.nirsoft.net/utils/shexview.html#DownloadLinks

Load it up and look for an entry called “BdShlExt” (see below) and right click and select disable.

Windows 10 send to menu Tweak

The send to menu is located below in windows explorer. Press Windows Key + R to get to the Run dialog Window and enter “shell:sendto”

You can add shortcuts to folders to this location by placing them inside this folder;

C:\Users\<your windows username>\AppData\Roaming\Microsoft\Windows\SendTo

Removing the list of Drives from the sendto menu requires a Registry tweak;

This is one of the most annoying things aboutr the sendto menu as it will list the drives on your system which most of the time isnt needed.

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoDrivesInSendToMenu"=dword:00000001
