Upgrading your computer power supply (e.g. Seasonic, etc) also can help keep some interference at bay too, but disconnecting from the grid helped some people. A big battery for your computer.lyar wrote: ↑26 Feb 2026, 00:49My uncle uses an AV Receiver when he uses his TV, and it is usually always on. When he watches TV and leaves everything on my game is not playable at all. The weeks he is away from home for work, my games feeling is considerably better overall, despite some inconsistencies. Also when the laundry machines are in use my game has this same inconsistent feeling, even if short-lived. I have had this input lag problem with my NIC disabled in device manager and on many computers, mice, keyboards, and monitors over the years in several locations in Vancouver BC so I believe I am dealing with harmonic distortion in my area
You might want to see the Electrical Interference discussion forum about offgridding your rig as a test. A 12.8V 100AH (1200 watt-hour) lithium iron battery and a kilowatt inverter can now be had for just a few hundred dollars (under $300 total if you shop around). And much cheaper to DIY than a Jackery Power Station or similar. Or just get any of those kilowatt-plus sized ANKER/Ecoflow power station on wheels (more expensive but you can take it camping or power your fridge in a blackout).
A giant version of your mobile phone power bank. A long-duration unplugged UPS essentially. But for a whole gaming rig that lasts about 3 hours battery powering RTX 5080 at 480Hz. Or more, if you get one of those bigger power stations on wheels about the size of a clothes hamper -- those bigger 3-kilowatt-hour batteries will power a whole gaming rig for about 5-10 hours.
This is beyond scope of this discussion forum topic area, so you'll have to discuss electrical-related latency issues in that other forum - viewforum.php?f=24
Be noted, some threads are a bit "out there", but dirty electricity do create legitimate performance-problems (interference -> error correction -> random jitters/latencies in various cabling like Ethernet or USB and even internally inside the computer, motherboard, and GPU -- performance throttled during interference situations, voltage instability, etc). With problems often still happening even if you keep your data cables far away from your power cables / power bricks / power supplies.
It may be solely on the DSL/cable line, but if you have fiber to the home -- you can get fairly good chances with a big kilowatt-hour league battery for your computer. Zero copper touching the grid (battery powering your rig + fiber media converters instead of Ethernet cable) and at least a two foot gap between the computer and the walls (keep away from electrical wiring). Put your fiber router into the offgrid bubble too. Get high end shielded USB cables and/or try a high-rated wireless mice/keyboard instead since cables acts as antennas from the mini-EMP's coming from elsewhere such as from home theater speakers, in-wall electrical wiring, and from dryer motor. Be noted, one may work better than the other (depending on whether your problem is wireless interference vs wired interference)
No electrical replies here to me please -- I temporarily waived the rule to reply to you -- any replies; please post in the other area.
