Just installed 1942 yesterday and noticed the same ping spikes. On my favorite server (ATF Hump Em & Dump Em) with Vista my ping is 22-28ms; with 7 it starts at 35, goes down to 22, then spikes up to 50 at times.
Perhaps this is due to the fact the server is located at USC? Since guys are preparing for finals traffic is heavier? Over the years I have noticed that traffic increases this time of the year. I tried another server, Moongamers, and noticed ping spikes.
I checked health of the internet between me and the server (SBC and NTT) and the latency was 47ms, which is a little on the high side, but there was no packet loss.
I reconfigured my AV, which was set pretty aggressively, removed myself from my wife's Homegroup, disabled most of my programs "update automatically", set all the Punkbuster apps and the game to run as admin, and Moongamers now seems fine; although, I did not do much testing, only half a round last night... but the ATF server was still spiking... again, USC traffic?
This afternoon I'm going to test again and if it's still spiking I'm going to try this reg edit, posted by pinstripe:
"lag" in online games with Windows 7
- Open regedit
- Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
- There will be an entry for network performance throttling, default value is 10; set it to FFFFFFFF hex (willl look like 0xFFFFFFFF to the right of the entry)
I'll let ya know how it goes...
