Big FPS boost on my system doing this

[Schorle 25]

I'm a little bit surprised I have not seen this on this forum (or maybe I'm blind...).

Just qouting official Asobo forum. On my system I'm gaining around 15 FPS using Airliners:

It’s super easy to try and you don’t risk to break anything in the sim. The file to edit can be found here:

MS Store version:
C:\Users\YOURNAME\AppData\Local\Packages\Microsoft.FlightSimulator_RANDOMCODE\LocalCache\Packages\Official\OneStore\asobo-vcockpits-instruments\html_ui\Pages\VCockpit\Instruments\Shared\BaseInstrument.js

OR

%localappdata%\Packages\Microsoft.FlightSimulator_RANDOMCODE\LocalCache\Packages\Official\OneStore\asobo-vcockpits-instruments\html_ui\Pages\VCockpit\Instruments\Shared\BaseInstrument.js

Steam version:
C:\Users\YOURNAME\AppData\Local\Packages\Microsoft.FlightSimulator_RANDOMCODE\LocalCache\Packages\Official\Steam\asobo-vcockpits-instruments\html_ui\Pages\VCockpit\Instruments\Shared\BaseInstrument.js

OR

%localappdata%\Packages\Microsoft.FlightSimulator_RANDOMCODE\LocalCache\Packages\Official\Steam\asobo-vcockpits-instruments\html_ui\Pages\VCockpit\Instruments\Shared\BaseInstrument.js

To edit the BaseInstrument.js file I suggest to use a code editor as Notepad++ or Sublime Text (both free). Backup the file making a copy on your desktop to restore it in case you encounter any problem.

This is the part to be edited (line 235 in my case but may be different):

 CanUpdate() {
        var quality = this.getQuality();
        if (quality == Quality.medium) {
            if ((this.frameCount % 8) != 0) {
                return false;
            }
        }
        else if (quality == Quality.low) {
            if ((this.frameCount % 32) != 0) {
                return false;
            }
        }
        else if (quality == Quality.hidden) {
            if ((this.frameCount % 128) != 0) {
                return false;
            }
        }
        else if (quality == Quality.disabled) {
            return false;
        }
        return true;
    }

and overwrite it to his new code:

CanUpdate() {
        var quality = this.getQuality();
        if (quality == Quality.high) {
            if ((this.frameCount % 3) != 0) {
                return false;
            }
        }    
        if (quality == Quality.medium) {
            if ((this.frameCount % 8) != 0) {
                return false;
            }
        }
        else if (quality == Quality.low) {
            if ((this.frameCount % 32) != 0) {
                return false;
            }
        }
        else if (quality == Quality.hidden) {
            if ((this.frameCount % 128) != 0) {
                return false;
            }
        }
        else if (quality == Quality.disabled) {
            return false;
        }
        return true;
    }    

All that is changing is that you are adding in these lines:

if (quality == Quality.high) {
if ((this.frameCount % 3) != 0) {
return false;
}

which are setting a refresh rate of the screens when in the cockpit (quality = high) and it’s setting a division of your screen refresh rate (144/3, or 60/3 or 120/3, whatever) and you can change that ‘3’ to be whatever you want. The higher the number, the smaller the end refresh will be and the better performance you should get but the more choppy the little screens will refresh.

Hope this helps some people to get better FPS. Surely helped me a lot!

Second option I'm worried...

Don't take people here too personally. Thanks for this i haven't saw it as well.

Thanks for posting this.  It is very clear and I am going to give it a go.

As roi1862 has stated.  Don't take things too personally as some people seem to lack patience and respect lately (although the above is probably more like lighthearted sarcasm I think), but there are still plenty of good folks here! 👍

I can't blame you for missing it as there is so much activity here due to the new sim, and the posts get shuffled down very quickly.

It's been posted everywhere and it works. On 60Hz, setting it to 3 will update the displays at 20Hz, which is borderline OK in the Airbus.

My intent was to be lighthearted as the OP was in writing "or maybe I'm blind".

No intention to be sarcastic or rude in any way.

Sorry if this passed through. English is not my mother language either...

No problem. All is fine, nobody got hurt 🙂

For 60hz screen, I found 2.5 to be balanced between performance and display refresh rate.

Our European sense of humour, which is sometimes involves light hearted sarcasm, can be misunderstood sometimes.  I love it, but it got me into trouble in Florida!  😄

On another note, I can't wait to try this little modification. 

If the displays lag too much afterwards, is it possible to alter the setting from 3 to 2?

Ignore the above question, kindly answered by omarsmak as our posts crossed.  I will try 2.5.  👍

The list of possible places to find the file to be modified is missing one option.

I chose to put the files for the simulator during installation on my G: drive in a folder FS2020 and this is where the file to be modified is stored.

I look in
G:\FS2020\Official\OneStore\asobo-vcockpits-instruments\html_ui\Pages\VCockpit\Instruments\Shared\BaseInstrument.js

Nothing wrong with posting something useful twice when we have dozens of threads with the same useless discussions spamming several pages on avsim.

Thanks for posting.

So having 50HZ(60FPS LIMIT IN MSFS) and NCP set at 25FPS what would be a good value ?

Thanks

If you read through the post linked and I know why your thinking its about Hz because, I did also, thats what was talked about but its about FPS not Hz. That is a huge diffrence.

I would love it to be Hz as mine is 120hz but it works of you FPS, read the other post and please correct me if I am wrong.

I am very positive it's Hz. I run 60Hz and the modulator is set to 3 - the displays update at 20FPS (I can tell). If it was FPS, it would be updating 10 times a sec and be extremely choppy.
