No input lag after Alt-Tabbing

[InputLagger]

So the fix for this is yet to be found it seems? This is wild, because I've been through 3 different PC's at this point and all have the same issue, even when all parts are completely changed. Annoying to know that my old 775 LGA system was smoother and much more consistent than my i9 10850K with a 144hz monitor.

did you already sold your lga775? maybe, this is time for comparison for both configurations?

Unfortunately yes, did it a long time ago. I'm still going to the office I used to work at as an IT and I remember every PC I would build/troubleshoot there would not have this issue and will check if my PC will do the same there and also compare to other PCs.

Might be.. Try enabling jumbo packets, packet coalescing, adaptive inter-frame spacing and interrupt moderation "Set to medium or above" in your ethernet's advanced settings tab. You can also increase transmit and receive buffers, and some other options that you can do through regedit that I can't think of right now. Theoretically, this will have a stronger say in the number of packets sent, maybe it'll work, who knows!

One more thing to try, other thank unplugging cable or alt-tabbing. Try the option "Speed & Duplex" force a renegotiate by going down to 100mb Full Duplex, then after a while go back up to 1.0GB Full Duplex. For some odd reason, everytime I do that, my hitreg becomes better in the client sided game that I used to play.

Thanks man, gonna try it out soon!

Peace of mind kind of thing.

Yea for this exact reason I have this enabled, so!:)

Hello, im curious what kind of mouse you are using? is it g pro by any chance?
And also could be possible that something in your home is disrupting your connection?
I have the exact same issue, when alt tabbing game is super smooth and feels perfect, also when i completly unplug my internet it, lag is gone, when i plug it back in etc ethernet cable , then its good for abit, for a game or 2 its works perfectly fine but it seems to get worse overtime, so im wondering if there is something at my home disrupting my connection? like could be for example some kind lamp which is in same cycle as my internet and pc or em i tripping?

I have Zowie ZA-12 (A version). Nah, I tried to disconnect literally everything in my house except PC and router and its still has this issue.
Yea looks like you have some similar problem dood.

Another question i have for you is , how far is your mouse away from your Monitor, are you playing with your arm fully on the table therefor
the mouse is closer to the monitor same for keyboard or is it further away like a wrist gamer? Let me know.

I have it closer to the monitor.

Could it be that that monitor is emiting EMI? what kind of monitor is it?
And did you try with a different Monitor?

[dopamines]

did you try another monitor? could it be interference from monitor? since you are so close with mouse?

I tried 2 different monitors - still had this issue

Can you test if it happens on only Online games or also offline? Make sure you test turning off anything network related.

It's absolutely my network problem. Ethernet cable 100% (not the cable itself but some interference that comes from the ethernet cable). I have a massive improvement whenever I unplug the ethernet cable. Even on desktop and even when I unplug and plug-in almost immediately (although improvement lasts like for a minute or so).
Not a bios issue, tested every setting possible that has smth to do with network.
Could it be a internet driver issue or any related to OS problem?

Also, I have to mention that I struggled with input lag for 4 years and recently when I cut out all the cables that somehow touched the ethernet cable (telephone cable, old TV coaxial cable) - I had the biggest boost that I've ever seen in 4 years. My game now is completely playable, HOWEVER its not perfect. I would say I fixed my issue for 70-80%. But 20-30% is still there. When I found out that it's somehow related to my ethernet cable I immediately cut out cables that I mentioned above AND changed ISP along with ethernet cable. Then I saw that improvement.

I have almost the same improvement compared to unplugging ethernet cable (along with alt-tabbing) when I don't touch the mouse at all for like a minute. And I think @Thatweirdinputlag get why's that. When I dont touch my mouse being on the server (in Valorant on the firing range) - I send 10 packets (for example), whenever I'm starting to move my mouse - I send 40 packets. The more packets I send, the more input lag I'm experiencing. When I'm alttabbing this process resets. I can record a video how it actually happens.
Sorry for my bad explanation and english but I think you get the point.

I changed my ISP; ethernet cable; router; the extension cord router connected to; ethernet cable that goes from my router into my PC (bought STPF-8 max shielded cable - didn't help).

i think i have the same issue when i unplug my router from the electricity the pc becomes responsive and smooth. first i thought its electricity but when i unplug my WAN port ethernet cable all the lags are gone. i dont know how many routers you have but mine is the switch ethernet that fiber connects to it and getting the internet from the isp then inside my house i have huawei router from the isp that giving me wifi , lan ports to pc to make internet etc. so in my opinion this lags comes from the streets where your fiber or main ethernet are coming from its giving emf,rmf,emi or whatever that going through your fiber connection or whatever you have.
The best things u can try is UPS on battery that u will connect only your router.

2.unplug your router from the electricity and try to play with mobile internet and see if you have still input lag. if its all good you have something going through your main internet connection, if this option didnt fixing your you it can be electricity its only my opinion i hope i helped and sorry for my english i hope its understandable

Most likely culprit is your router transformer/wall adapters. You can buy better wall adapters or try ferrites. These ferrites may help (mix 75/J 150 KHz – 10 MHz or 30 MHz). Mix 31 (1 - 300 MHz) could also help, it it easier to find. Mix 77 (100 KHz - 50 MHz) is a new mix and very hard to find. I recommend Ferrite Snap Ons.

You should buy bigger ones than your wiring. So you can twist (turn) them at least 2 times or more.
Those ferrites should be put on wall adapters power wire, Ethernet wire and maybe to your mouse wire.

You can also test those wall adapters with your AM radio. Higher the noise the worse those are.

"RFI can creep in from switching power supplies, wall power adapters, dimmer switches, touch lamps, appliances and just about anything near Ethernet cables. The RFI generated internally by the device can be radiated over the Ethernet cable. Once RFI is in the Ethernet cable it acts as an antenna and radiates RF signals. Proximity of transmitting antennas near internal wiring can cause interference that gets into Ethernet cables (My comment: These also mean wireless mouse and wireless keyboard USB transmitters. Solution add USB Extension cable). Even if the RJ-45 cables are “shielded”, and especially if the shield is terminated at both ends of the cable, then the shield becomes just another conductor which can receive unwanted signals and reradiate them just as any other wire in the cable might do."

"Always use RF clean power supplies. Linear power supplies are usually better than switching power supplies. However, most wall adapters do not have proper filtering and can cause significant interference problems."

Has anyone experienced this? Because it driving me crazy, I dont have that real heavy input delay that I had before, but its still annoying because I know how I should feel this input delay when I'm alt-tabbing.
if anyone has any advice please let me know!

You know i read your post about a month ago and immediately called it Placebo.

2 days ago i accidental pressed windows key while in game and then BOOOOOM best game in ages.

This just dosent make any sense at all, but it works
