I use MFDE for gagues and RTT for MFDs, both client/server to extra monitors. MFDE and RTT client are on a second computer. No lag issues whatsoever, but my second computer is hard wired to the network. Never trusted wifi/bluetooth reliability for my sim.

@oakdesign @Fluke thanks – looks still actively maintained, and it’s C# so I’ll open an issue and send a PR if necessary

@airtex2019 said in 4.37.6.0 RTT Lagging Output:

@Fluke what is the ded/icp app … is it open-source?

We made some efficiency improvements to shared-memory export, last year, but individual apps will need to be updated to take advantage of it

I have an app that worked fine with early 4.37.x versions. What were the changes, could you share a bit what that entails when reading textures from memory ?

[airtex2019]

@jayb sorry my mistake - I think these RTT perf improvements only went into the 4.38 branch

tl/dr there will be a Win32 event object, for shared-memory sections, that one can call WaitForSingleObject() on, to synchronize reader-loops with the writing

entirely optional (won’t break existing RTT clients) but if used, should greatly reduce CPU usage by rtt clients, and/or improve latency and eliminate “missed frame” jankiness

@Arty, this is exactly what I was searching for and it worked. Mind you, since this is RTTClient64.exe, even though I followed your directions using the numeric values (doesn’t matter if it’s hex or decimal value since they should translate to the same binary value), the value needed for “5: Above normal priority” needed to be changed to “6”. Confirmed in the Set Priority in Task Mgr/Processes which indicated “Above normal”.

This link (https://answers.microsoft.com/en-us/windows/forum/all/how-to-permanently-set-priority-processes-using/df82bd40-ce52-4b84-af34-4d93da17d079) documents the values used in Win 11:

Thanks a bunch since it did eliminate the perpetual changing of the “Set Priority” in Task Mgr.

@D_Lourdes Yea I saw that 5-6 thing… I searched it a bit but on three different references and two were microsoft ws saying 5 is the correct value… lol go figure…

@airtex2019 ok cool so no changes before 4.38 ?

[kungfoo]

@airtex2019 what are these changes to rtt export and what do i need to do to profit from them?

@kungfoo will reply in DM
