Micro stutters

I worked on this a good bit last night and I now do not think underclocking helps. I was however able to minimize it as much as I think is possible until DICE can look into this by capping my framerate right near where the "99% fps" maxes out at. I was capping at 119hz, but after analyzing the game last night my "99% fps" was maxing out at around 95fps, so I dropped my frame cap to 98hz and the micro stutter was far better. 

OK, I have been working on this more and now I have doubts about my router. As mentioned I have Comcast 3Gb symmetrical internet. The Juniper ACX2100-AC comes with a 3Gb fiber connection and a 1Gb copper connection for some weird reason. So I hooked my PC directly up to the 1Gb copper connection and now I no longer see the micro stutters. So now I get the fun task of figuring out why my Ubiquiti UDM Pro is causing problems in BF2042 when I see no issue in any other game like this one. I have played countless hours of COD Warzone without a single hiccup at all. My theory is that the fq_codel QoS function in the UDM Pro is somehow delaying packets. fq_codel is a drop tail method of QoS so it could be that I just need to set up a firewall rule that ensures my PC is first in line no matter what. I'll keep y'all informed of my analysis.

I recommend if you are experiencing the micro stutters to try your connection directly to your ISP's modem and skip your firewall as a temporary test so as to not burden DICE with something that may not be their problem.

In bfv i had the same problems you described.

In the networkgraph i had little packetloss, not enough to trigger a warning symbol in bfv but enough to stutter. 

speedtest were all good, but using smokeping and pingplotter i found out that my router was the problem. 

I bought a new one and since then i did not have a single problem. 

OK I am fixed regarding the micro stutter issue but I'm sorry it won't fix the rest of you guys' problems. ☹️ Mine was a fiber GBIC issue.

One was the uplink to the UDM Pro from my 10g switch, the other was the uplink from my 10G switch to my core 1G switch. One or both were part of my problem.

The only thing I could suggest for the rest of you is to check your cables as I did as they can and will fail. Good luck!

Same problem for me with MSI RTX 3070Ti SuprimX, I7 11700K, 32Go 3200mhz, ssd. No OC.

Same issue here RTX 3080 AMD ryzen 5600g Samsung 980 pro ssd. no overlays. gsync monitor and correct framrate in windows. good cable. tested on every settings Level gsync/vsnyc/pre rendering... in off. every other game (bf v too) works fine
