FSXAssist 1.20G a SkyPilot Performance Product
Download FSXAssist

Welcome to FSXAssist
FSXAssist is a fun / flexible FSX tweaking and configuration tool that is designed to help novice and advance users to get the best performance out of FSX.  In a nutshell FSXAssist provides 5 core functions.   First and foremost FSXAssist is an FSX loader program providing for a flexible way to run FSX and any Addon applications. Second, FSXAssist provides a way to dynamically set Affinity Masks (core usage) and OS priorities between FSX and any Addon applications.  Third, with FSXAssist you have a simple way to assign the most common FSX settings that have the most effect on performance and finally, FSXAssist includes extras like autosave, flight device connect protection and crash recovery.  The best part is when you have found your best settings they can be used every time you run FSX!

Requirements
In order to run FSXAssist you must have the following: Getting Started
Download the FSXAssist installer program from FSXAssist_Setup.exe.  Run it as Administrator and confirm all installer prompts.  After installation you will have 2 shortcuts - one to run FSXAssist as configurator and loader or to just run FSX (FSXAssist_Run).

Addon Applications
FSXAssist knows about 2 classes of Addon applications - those in the FSX registered exe.xml file and those that you add manually through the UI.  Both types are treated the same during the FSXAssist loading process as far as Affinity Mask and OS Priority goes.  The main difference is when you remove an application in the UI.  The exe.xml apps are marked as disabled while the manually added apps are simply removed.  Note that the applications are not deleted but just removed from the list of applications to run.

Now the thing to remember is if you removed an exe.xml application and want to get it back you have 3 options. 1) edit the exe.xml file and set the disabled attribute to 'False', 2) add it maually with the FSXAssist UI add Addon button or 3) restore your original FSX configuration files using the restore original configuration button.  

Controller Dropout Fix
FSXAssist will use Simconnect to restablish the startup controller at 1 second intervals. This has worked well on Windows 8+ in testing. While we cannot gaurantee that this fix will work for you we suggest that you enable the SimConnect and Messaging options and check your power axis movement to confirm.

AutoRestarts
FSXAssist will determine if FSX is no longer responding and will initiate a restart with the following: 1) all Addon applications will be terminated, 2) FSX will be terminated, 3) all FSX crash messages will be suppressed, and 4) an FSX restart will occur with the last saved flight and with a subsequent reload of any Addon applications.

AutoSave
AutoSave was added to FSXassist to facilitate the AutoRestart feature but is a nice thing to have in most situations. To enable make sure that the SimConnect option is selected and then set the number of minutes that your want to use for AutoSaving. The default / recommended setting is 3 minutes. When a save occurs you may notice a 1 sec bump in external view but usually nothing in cockpit view. The importent thing is to set Enroute.flt as your default flight in FSX.

Running FSX Realtime
Months of testing has shown that a nice FPS increase is possible when using a Realtime Priority for FSX.  We sometimes hear the SoundBlaster driver break up with Realtime but we can fix by 1) toggleing FSX sound off / on or by 2) setting FSX priority down to HIGH but that setting can cause ground blurries to start showing up. Setting FSX priority back to Realtime fixes the blurries given a bit of time.

Features (see image below)


Running FSXAssist Realtime
After you click 'Run FSXAssist' and if SimmConnect is enabled then you can ALT TAB back to FSXAssist (or any app). If after up to 3 minutes elapse and you do not click on 'Run FSXAssist', then FSXAssist will automatically set focus back to FSX. This is handy if you (like me) forget that you are running FSX or (like me) you have to click on the taskbar several times to get back to FSX. Always click 'Run FSXAssist' to get back to FSX cleanly. That will also restart what we call the 3 Minute Timer (3MT). The 3MT is also used for the Controller Dropout Fix so it is important.

Running FSX Realtime Revisted
The theme here is time and mostly timings. Time and time again we at SkyPilot have proven that a Realtime FSX Priority will prevent blurries and generally improve FPS. The reason is that a Realtime Priority tightens the FSX processing loop simply because the OS will favor FSX for clock cycles and I'm pretty sure that this is done at the micro-code level. IOW, FSX can get things done faster and that includes all of the FSX threads like the one that renders scenery tiles. You will want to set the Frame Limit setting to 0 and the Level Of Detail setting to 7.5 to get this to work. This configuration funnels more clock cycles to the tile rendering engine for sharper textures.

Real Life Results
SkyPilot computers are generally considered high-end systems running at 4.8ghz.  Since we are avid FSX'ers running all the best stuff like RealAir planes and ORBX scenery you may be interested in how we use FSXassist.  To be honest, FSXassist was created mainly because I wasn't happy that EZDOK was running at a higher priority than FSX.  My discovery was that EZDOK runs perfectly well at Normal priority while FSX is Realtime.

As far as Affinity Masks, I'm still a fan of keeping all Addons on their separate core so I force all Addons to core 1 (Affinity Mask = 1) and leave all other cores to FSX. This lead me to another discovery to use HyperThreading with an LOD of 7.5 (with unlimited for testing) which eliminated any blurries. 

Otherwise everything works great using the settings in the FSXassist screen shot in this help.

Finally
If for some reason you find that your Affinity Mask, Priority settings or even your registration key are not saving then make sure that the FSXAssist.exe properties are set to 'Run As Administrator' for all users.

I hope that FSXAssist turns out to be a great tool for you!  It has been a fun project for the team.
