Why is it that my internet connection seems to run smoothly whenever I'm online (browsing, watching videos/ streams) but as soon as I start any online game, I have lag spikes all over the place?
The game runs without a problem, but around all 2 seconds it randomly laggs for a few milliseconds.
All of this is, while the Ping overall is very low (30-50ms) and it does not show an increase of ping while it is lagging
Btw. My PC is connected to the Internet via
[Router] (WLAN)--> [WLAN Repeater] (LAN)--> [PC].
The WLAN Repeater shows 4 out of 5 connection bars and the problem only occurs since around a week, before that it ran without a problem.
Maybe someone has an Idea, thanks in advance 
Edit: Already checked the Router, problem even occurs when there's no other person using the network

Games are much more sensitive to stuff like jitter and packet loss. You can have a half decent browsing and online video experience with a bad connection.

Is there a way to find out if one of those things could be the problem?

There are tests online. For a simple test you can open the command prompt and type "ping www.google.com -t" without the quotes, it shouldn't have any time-outs and the ping time should be very similar between runs on a good quality connection.

Why do I sometimes have to redownload custom maps online? I have limited bandwith. How can I stop that? (There are enough people with limited bandwith or mobile internet - it's modern.) (talking about the same version, not a patch or upgrade).
|
I think they're generally not the same map. There's some slight difference made to the file each time.

Is anyone else having trouble downloading stuff inside of sc2 sometimes? It seems that some days i can't download arcade maps faster than like 20KB/s which makes it impossible to join frontpage lobbies; others it works fine and i download a 100MB map in a couple seconds.

Whats the difference between PCIe and SATA for a SSD? And did I make the wrong choice of having 2 SATA SSD's?
Just read about this in an Anthem review discussing loading times. Never heard it before

PCI-E or m.2 based SSD's can be much faster in some stats than sata 3 based SSD's but they're usually more expensive too and those benchmark gains often don't translate into real world performance improvements
3d xpoint PCI-E SSD's came out recently, that's a new technology with far greater advantages that are more likely to show up on real world tests but it's a lot more expensive.

Thank you very much! I will keep an eye out in the future

This is what it shows, an online Test only says it's 1ms jitter though.
The thing I'm wondering is why it's only recently, is there any solution?

~20ms is fine, those spikes of +300ms are an issue. You should be looking to determine where that's coming from, usually it's a poor connection to your router (like wireless with bad signal and/or interference) but it can be a range of other issues including service provider and router problems.

I don't know what the problem is, but this shows that it definitively exists. Those 300s and 400s are the problem, your ping is way to inconsistent. A 400ms ping result is basically a 0.4 second lag spike. And any connection to something else than google is usually slower.
As a comparison, mine is consistently between 25 and 45ms (most around 28-30) without any further outliers in about a hundred attempts. Yours seems to be generally fine, but spiky.
Do other PCs in the same network have the same result? Than it is probably the fault of your ISP. Do they not? Than it is something on your PC. And honestly, it could simply be your ISP fucking something up. Would you mind telling us what type of connection and ISP you have?
|
If you do eventually determine it's your ISP's fault, using a VPN will sometimes help.

Thank you, I'll try out a few things

Wifi repeaters absolutely wreck throughput and latency since they're competing with the AP for the same channel. Try to avoid the repeater if possible.

I had a discussion with someone about saving energy and want to verify my position. He claimed that in order to save energy, one should buy a laptop instead of a pc because "an efficient laptop uses only a tenth of the energy of a desktop pc".
The problem I have with this statement is that if we compare power usage at similar performance levels (which I would describe as efficiency), I do not see why a Laptop should be more efficient than a pc?
On the contrary, I would suspect that desktop pc's have better performance/power usage ratios because of better cooling. Or is there something I am missing here?

For a PC, power efficiency is not that important, while it is a major engineering constraint for a laptop. If a PC uses a bit more power, it just uses a bit more power. If a laptop uses a bit more power, it lasts a smaller amount of time on one battery charge.
As such, i would assume that laptops are more strickly engineered for smaller power use. You are correct that the situation gets muddied by the fact that laptops are also less powerful than desktops (on average).

Pretty much this: laptops are less powerful, because they are required to last a minimum amount of time on a battery, and perhaps even more importantly: require all the hardware to fit in a far smaller case, in which overheating quickly becomes an insurmountable problem if you simply try to squash a desktop's performance into it.
That said, there are definitely things that make a notebook use less power than a desktop:
1. Screen size and brightness. Notebooks have smaller screens and you'd generally use lower brightness specifically to save power. You can reproduce this with a desktop, obviously, but most people don't. Screens use a fair amount of power.
2. Laptop hardware is designed to be power saving (e.g. throttling GPU unless it is explicitly needed). This results in far more aggressive energy saving settings. As long as you don't change these, they will save power.
3. Power saving settings. Not only at a hardware level, but also at a software level, power saving settings are generally more aggressive in laptops. This is easier to equalize between systems than the hardware settings, but unless you actually do that, desktops will use more energy.
In other words: desktops don't necessarily use more power than laptops, but laptops are designed to be energy efficient out-of-the-box whereas desktops aren't.

Laptop parts do tend to be tuned for higher efficiency but the advantage is not that large and you can also tune PC parts as such if you wanted to with only a minor disadvantage. Many of the parts in laptops vs PC's are actually the same physical hardware.
Cooling is a factor in efficiency but that's also small, if you run a GPU 20-25c cooler then the efficiency advantage is maybe 10%.
