PC Tips for performance improvements when playing with a friend?

Hey guys, i want to play 7 days with my friend who lives in china, while i am germany. For him it keeps lagging when i host the game, while my game runs fine.

Since i am not very familiar with IT-related stuff, are there any tips that might help him improve the performance?

He got a high end pc with a good graphic card, so it might not be performance issues due to his pc setup. I got a "regular" pc with a good but little bit outdated graphic card. Would it maybe help if he hosts the game?

 
Whoever has the better CPU, RAM, and storage should be the one hosting. 

Also note that I will take anyone saying they have a "high-end PC" with a grain of salt.  I've seen where people got scammed and ended up with hardware that was five years obsolete. There is also a great issue with all the new Intel Chipsets where processes aren't assigned properly, and it will put the game onto the E-Cores instead of a performance core.  Intel has known about the issue for years and is still barely doing anything about it.

More specific information on your rigs would result in better tips. 

 
Your biggest problem is lag time between China and Germany.  To put it like an engineer, frankly, the speed of light sucks.

Agree with SylenThunder that best CPU and RAM should be hosting.  These days I'll assume you have SSD storage.  But your biggest problem is how long it takes network information to from China, to central China ISP backbone, across a half of Asia and part of Europe to a German ISP backbone, then get routed to your server, and then all that back again.  While it'll be measureable in milliseconds, its going to be high double digit, maybe triple digits.

Even here in the US, I play from the Southeast to a friend's server in the Northwest. He's about 2000 miles from me (3200 km) and I used to get 30ms and 40ms round trip (ping to ISP was low 20s on fiber at the time).  And while 40ms is a really short amount of time, its also 1/25th of a second, which is an eternity in terms of timing hits as a zombie closes on you.  Over 100 ms will be very painful every time you open a container or swing at a zombie.

Not that you can't maybe find ways to optimize the small parts in your control, like your own wifi, but the pure distance between you two is going to create a minimum round trip that you can't do anything about.  If you could, theoretically, pay for a hosting server somewhere between you two, it might improve, assuming you can host in a country that neither Germany nor China would block internet traffic to/from.

The biggest problem is the Great Firewall of China. It itself gives a delay of 200 milliseconds.

 
When I played DOA Online, I traced to the Beijing and Shanghai servers. When a packet arrived in China, the ping immediately increased by an average of 200ms.

 
I`ll agree with all above mentioned, but I`ll add my 5cents. The average home internet in Germany sucks hard and is crazy expensive, currently working with German company, when guys work from office its okay, but as soon as they go home it becomes awful 😁, and we`re talking IT guys 😁. And yes, the best option for you guys would be to rent a server somewhere in between to host the game for you. This would half the distance lag, and you will then only be bound by quality of your own connections.

Debatable. When I did the tracing from Moscow to Beijing, the packets could go through both Berlin and New York. Moreover, the route depended on the time of day. It seems that the choice is made by routers depending on the load on a particular highway. And it depends little on physical distance.

@%$# happens, but I suppose quite soon you'll have a common intranet with China and North Korea 😁
