Spring RTS Engine

Cross posting this from http://zero-k.info/Forum/Thread/5704

Just came back to zk, but in my first game it was lagging very badly. I kept getting spam in the chat window something like "Error, discarding incoming corrupt packets". Anyone have any ideas? This makes zk almost unplayable.

Infolo.txt pastebined below.

[f=0000000] Error: Discarding incoming corrupted packet: CRC 117, LEN 6

i never saw so many CRC corrupted packages. do you have a personal firewall or something similar installed? is your network card maybe broken? did you check event log about network related errors?

I had windows firewall running, but turned it off and was still getting this spam. IDK if my network card is broken, I can play other games just fine, not seeing unusual amounts of lag, or any packet loss.

I have windows 7 64bit. From quick googling it doesn't have event log(think that is xp), but i checked event viewer and it didn't seem to show anything for the times i have tried to play zk/spring.

My mother board is this one. It has a "Killer E2205", which comes with some software. Haven't really poked around in it, but it did have spring/zk lobby running at it's highest priority settings.

Microsoft Windows 7 Business Edition, 64-bit Service Pack 1 (build 7601)
OS: emulated 32bitmode

Is it supposed to be like this, could that be problematic?

did you try to update the "killer" driver?

imo it kills your packets

285 MB for a network driver is wtf... as the hardware setup seems very uncommon imo & we never heard about such a bug its very likely its the hardware. but atm this is only a guess, hard to verify. sadly there is no changelog of the network driver.


@knorke: this should be normal...

Wow that's a lot malware (note the winxp32 drivers are only 6kB!)

I do have the latest drivers, and most of that is for the network manager utility. I tried, manually disabling it, no luck, then just killed the process in task manager, and it still is laggy.

I have the same problem. Haven't been able to play since mobo upgrade.
Also issues seem to be limited to springrts. All other apps/games run perfect.

I think you need to provide more info. I also have Win7 64bit and I have no issues.

As mentioned before springrts is the only application that has issues.

Killer is the ethernet technology where you can have custom packet shaping and prioritizing stuff right? Maybe you need to tell it that Spring is a game and to leave it's packets alone or something...

buy a 5$ gbit ethernet pci(-x) card to solve this... imo debugging this problem is a bit out of the scope for spring engine devs as it seems only related to the "Killer" ethernet card/drivers and no engine dev has such a card. yes, would be great if someone with such a card could find the real cause & fix it, but imo we can't.

when googleing disabling rx/tx checksum checksumming could help.

afaik spring doesn't do any special when sending/receiving network data, it only verifies checksums but those broke for some reason with this card.

Your network card (http://www.killergaming.com/solutions/Embedded_Ethernet) manipulates the network packets without the operating system (or spring) knowing about it. https://en.wikipedia.org/wiki/Killer_NIC

Look at the FAQ of your product: http://www.killergaming.com/support/Knowledge_Base

The problems with Skype and QQ Chat are probably similar to the ones with spring. Try to change (or disable) priorities for spring in the settings like described for QQ Chat, try disabling everything fancy the card can do for spring.
