Hi folks,

Just bought the RXP GTN 750 for P3D. I noticed that some aircraft developers have the follwing line in RealityXP.GTN.ini. The RXP manual does not seem to provide documentation for this setting. Can someone chime in for what this setting does and what is the default value?

ReduceRate  = true

BTW I can confirm the latest RXP GTN works great with Trainer 6.62.3 under Windows 10 Version 2004 for both P3D and X-Plane, even though the stand-alone GTN trainer lags quite a bit. Great work RXP!

 

Thanks,

Zicheng Cai

Thank you for your kind words!

It is documented p13 of the RXP GTN User's Manual as "Use Half-Rate screen Update" and it is meant to accommodate lower specs PC. It basically lowers the GTN native screen refresh rate from 30fps to 15fps.

Default value is false!

I'm wondering whether this would explain why some are reporting the RXP GTN appears sometimes 'laggy' when compared with another solution. If they are using the same aircraft this can explain a lot.

I'm surprised some aircraft vendors are enabling this by default. Which aircraft are these?

FlySimWare Falcon 50 and Learjet 35A. This is under [GTN_750_1] section for both aircraft.

Ok, you might want to tell them!

I'll do on my end as well.

After setting ReducedRate to false, the GTN is noticeably smoother compared to before. This observation supports the hypothesis

Thanks for the info! I´ll try this too in here. A2A planes has this parameter to "false" as default.
