I just had a similar experience as the OP:  with all but Enroute set to level 3, flying into FT's KLAS just now I noticed upon landing and taxi in my native rate set at 30fps x2 w/ FG or 60fps.  I changed to wide open because it was evident it was having a bit of trouble even maintaining native 30:  the unlocked rate was 62 or so which I knew was way lower than typical in this scenario.  So I simply shut BATC down and voila the native rate jumped to 49, or 98 with FG enabled.

After ending that flight, reboot and off to KPSP.  This time I monitored wide open rate.  Prior to starting BATC:  48fps native.  After starting BATC and waiting a few secs for all traffic so appear, which I set at 3 except for Enroute at 5:  frame rate stayed the same at around 48fps x 2 or 96fps w/ FG.  I continued thru pushback by GSX and rate stayed around 89fps w/ FG.

Who knows why the severe deterioration happened at KLAS.  It was a short flight as well from KSJC.  

BATC is an experimental software that is in active development and not yet fully released.  You should be posting this information back to the developer directly or via their Discord set up specifically for that.  Also consider purchasing when it does get released as I am sure many of these issues will be resolved.

Have you try to reduce fps from batc setting menu? Default is 60, try lower it

Haven’t but will try

There was an tp BATC update today for me anyway 🙂

Who discredited you? And I don't see anything wrong with the response from the dev - what specifically are you taking offense with?

Just to be clear, you don't have the Traffic Injector for FSLTL active at the same time as running BATC - correct?

Sorry, that post did not include you I was just trying to reply to someone else who claimed that I’m stupid and I don’t know how frame generation works I mean if I did not get an offense from that what do you think should i do ?

Same here. I keep traffic at 3 and my PC still suffers a FPS hit. Going beyond 5, forget it, a stutter fest. In short, you are not alone.

That’s what I’ve been trying to say the app is super intensive even intensive more than FSLTL. It feels like you’re rendering a whole project in blender while playing MSFS

And no, FSLTL injector is not running like I stated earlier I read their knowledge base and actually ask them personally what are the do’s and don’ts?

Nope even on 30fps it’s not helping

So you have the same performance running BATC Vulkan, DX11 or OpenGL?

What models/liveries are you using? You could try scaling them from 4k to 2k (both aig and ftl models can do it).

How did you setup @target fps@ in BATC? A too high value can impact performance too.

On my system, running triples 4k, 14700kf and 32gb ram, i can get 40fps at LFPG with batc traffic sliders between 7 and 9.

P.S.

Since you say you-ve reflashed your bios, and 13900ks is quite power hungry and running hot, how did you set up power limits, voffset, llc and vid? Too long to write here, but if you left everything default or unlimited, that`s not good. Check for intel reccomendations, then with hwinfo or similar, look at vid, temp, frequencies and such.

 

I did scale the models to 1k still performance issues keep reoccurring 

 

As for adjusting my bios, I used Guide by SkatterBencher very well known

I tried limiting the FBS to 30 in the app so the performance should keep occurring setting it to 120 FPS again does not help

Yep 👍

Something's wrong with your system.

What's your specs and BATC traffic settings?

Watched part of that video. I wouldnt use such approach now, expecially with newer bioses and all the story about intel chips degradation. If I`m not mistaken, he still kept unlimited power limits, and quite a high vid. I`d keep a more conservative, safe and stable approach, without risking chip degradation, or making it run too hot and then clipping and cutting frequencies.

 Back on topic, did you try running autofps app? At least for me, since running triples 4k is quite heavy, made a big difference for having costant fps.

I tried the app in the past, but caused me performance problems later
