Re: Receive Side Scaling - latency hazard?

Well, it's working, I think. With QoS packet-shaping enabled you are downloading simultaneously and only seeing a rise from 25.7 to 27.5ms of game latency. That's pretty trivial, 1.8ms isn't enough to lose you a server 'tick' in either direction. If you weren't using QoS I'd expect to see your laten...

I don't really see a significant price difference between shingled archive/surveillance drives and perfectly decent NAS/desktop PMR drives though. Maybe 5-10% cheaper, if at all.

Re: Recommendations for an 8 TB HDD

I'm chiming in late, but honestly anything with SMR should be avoided, even in those instances like surveilance or cold data storage where SMR's downsides aren't so important. There's simply not enough capacity gain from SMR to make it remotely worth even one of the many downsides, and there are SO ...

Re: Receive Side Scaling - latency hazard?

I'm curious what you mean by download traffic being more 'bursty' I think you're misquoting someone else. IMO it's not bursty, it's the fact that your router has RX/TX buffers and flow control, so even if you're nowhere near bandwidth cap, there's added latency from the router processing the buffer...

Re: Receive Side Scaling - latency hazard?

Downloads of any size affect your latency because there's a queue of non-gaming traffic in the buffers that the gaming packet has to wait for. What you need is router firmware that has application-specific QoS. Sadly, I can't recommend anything consumer that handles it that granularly but DD-WRT is ...

Re: Curved Screens General Impressions + How does it look with 3?

At work I have a non-curved 42" 4K display, and I find I don't use the last few inches on either side very much, because they're too far away and the viewing angle is non-optimal. Maybe a curved screen would help a little with this. It absolutely would help - both with viewing angles and also ...

Re: Receive Side Scaling - latency hazard?

I still think MTU is irrelevant and best left at the defaults your ISP sets. Typical MTUs on modern connections are around a kilo byte or two, whilst bandwidth is usually multiple megabytes a second. That means that making wild changes to your MTU has a near-zero effect on your latency. Let's spitba...

In terms of distortion, don't worry about it I've gone back to a flat screen at the moment (previous was an Acer curved VA 144Hz) and there's no difficulty dealing with the curved screen. Don't forget, the image you see on a flat screen is also distorted if you look at any part of the screen except ...

Re: Curved Screens General Impressions + How does it look with 3?

The curve radius is usually 1800R or 2000R. No way he's going to sit 1.8M from the screen, right? The side screens will be at the wrong angle if he sticks to the screen's curve only.

Put OpenWRT on the C9. I've done this with dozens of C7's and it becomes much less of a buggy mess. The only drawback is that OpenWRT doesn't support the hardware TCP offload feature on the board, so you can run into performance issues if your internet connection is over a few hundred MB/s.

Run coretemp ( direct-link to standalone executable without bloatware) to see how fast your CPU temperature fluctuates. You can set it to poll in 0.1s increments. Run some typical software/games with coretemp visible and see what the "slack" in your system is. For me in an air-conditioned ...

If you set the fan step up and step down to a long time, it will make big jumps in fan tone as there's almost a a guarantee that the temperature will be very different between step changes. Put this value at 0-3 seconds, IMO. I would manually edit the fan curve so that your normal idle temperature (...

Yeah, in those sorts of games at those sorts of framerates, you're looking at a Vega56. Going from 80-90fps freesync to anything less than 120Hz without VRR is going to feel horrible. So yes, a 1070Ti might be 30-40% faster, but you're not going to get any real-world smoothness benefits in your gami...

Losing Freesync is fine if you can reliably get to the monitor's max framerate without issue. The problem you have is that the RX480 probably gets you somewhere in your freesync range at all times, whilst only delivering around 70fps. Nvidia cards are likely to frameskip on a freesync monitor unless...
