Windows Really Laggy Multiplayer

If this is happening on a lot of games, then ever thought of doing windows refresh..? (or reset, what ever you want to call it..)
And then if it still happens, upgrade your pc.

 

KAG is CPU, not graphics heavy. Your graphics card is more or less irrelevant, and amount of ram is borderline (4gb is much more than enough, unless you're running a web browser or something in the background)

Your single core cpu performance is the #1 important factor - your sisters "toaster" might have had a reasonably high-clock desktop cpu regardless of what operating system it was running. That said, any intel i5 or greater last-5 years CPU "should be" enough to run KAG ok. AMD cpus have a terrible history with KAG, unfortunately.

Some possible optimisations and diagnostics:

• Try turning off help, with f1 - the help code hits the disk way too often and needs to be optimised.
• Run faster graphics and kids safe mode - this only helps because it'll cut down on the amount of particles that the CPU has to simulate.
  
• Don't run other programs at the same time as KAG - especially things like web browsers, virus scans, and video playback.
  
• Turn on the network graph (hit home to open the console, and type /n_graph 1) - if there's big "holes" in the graph, your connection is unstable and you'll get awful lag.

 

If it's your connection,

• If you're using wifi, make sure you've got good signal without much packet drop (if not, consider a signal booster, google should help with improving your wifi link) or consider upgrading to a wired connection.
  
• If the connection is shared shared (sounds like it is) make sure someone else isn't like, patching games, streaming hd video, or torrenting stuff unless you've got amazing internet. Depending on your router, the machines involved, and a heap of other unpredictable factors, someone else's connection might be given priority over yours (especially because KAG uses UDP which is good for low latency but isn't given priority in high traffic situations).
  
• Make sure you're not doing the above either, very easy to grief yourself by listening to music over youtube or patching steam games on a low-bandwidth connection :)

Take a look at that.

 

This hints pretty strongly that it's not network related. You still haven't told us what CPU you have :)

 

Model name, not just the company who made it.

(type up System information in file search)

Having a AMD CPU does not make kag unplayable.

AMD is just a company who makes CPUs, like Intel, they do CPU's at a cheaper price, but intel comes with a lot more features

The more cores and clock speed you have on a CPU the better.

 

well, your issue is with your computer since you are lagging in singleplayer. from what you gave me, i can see you have a 6 year old, entry level amd apu. there are 2 things: kag uses mostly the cpu, so the cpu is very important in terms of performance. whoever was optimizing kag's engine, was likely using an intel cpu, which is why intel cpus perform much better compared to amd cpus.
tldr: your cpu is not good enough. you dont really need an intel one, but it will probably run kag a lot better
