Re: Can private companies use license plate scanners?

All good points. The key information the university is dealing in is students' off-campus physical addresses, non-university-provided email addresses (when they can get their hands on them), and phone numbers. It doesn't violate FERPA, but still goes well beyond both student directory material and e...

Re: Can private companies use license plate scanners?

I'm just pointing out that complete deception is, for the most part, simply unnecessary. So, if the big conspiracy (which internal leaks could reveal, as you mention later) is superfluous and most of the mechanisms by which they do this are publicly knowable, why posit something that sounds like pa...

Re: Winter weather

CO/WY/NE, and it really does depend on wind. The very coldest days stay significantly subzero but tend to be calm, and that's not a problem if I'm bundled up decently. +30F with a 20 mph wind is at least as bad, IMO, and +10F windy days are the ones on which I really don't want to go anywhere.

That implies the OP should get a new CPU, which would probably be a terrific waste of money.

A properly functioning 4790 doesn't behave anything like this.

The issue is the system usage is across all 8 threads, presumably from the video driver, taking ~20-30% of each CPU thread, i.e. ~40-60% of each physical core. The non-system portion is about 60% of 1 CPU thread. How did you determine those two o...

Yeah, most older CPU-bound games are bound up on one core (WoW being a prime example), but there are a handful of new games that are now being bound by the number of cores/threads. It's a lot more than a handful if you're on 2C4T. Even Skyrim is noticeably faster on 4C4T than 2C4T unless you want t...

Re: CPU vs GPU Bottlenecks

An R7 1700 is 8C, 3.2 GHz (in practice), and ~65W (fairly accurate in practice). They're doubling SIMD width from that, but it's also a much better process. I wouldn't be surprised if they still can't quite make it to 3 GHz (depending on the process' V/F curve), but 2.5 should be easy and 3.0+ is pl...

I'd agree on control, but in practice I almost always just turn down settings until I'm CPU-bound (or all the way to potato in the case of twitchy FPSes because it still helps latency even if framerates don't improve). My target framerate is always whatever the CPU can manage, and if graphics have t...

Re: CPU vs GPU Bottlenecks

Being CPU-bound gets you less consistent frametimes, as you're seeing, but being GPU-bound often increases latency. There's a lot of personal preference in it. Getting both consistent frame delivery and ideal latency for a given game often takes a framerate limiter, but a lot of gamers recoil at the...

No, it's still plausible. CPU-side, they could, but they'd have to have a pretty good reason to. If they want to standardize on 8C dies everywhere and are expecting good yields (8C Zen2 will probably still be tiny in mm 2 ), that might do it. If 7nm's high costs are focused more on creating masks an...

Re: Bad eye strain with new monitor

The inversion thing is that each pixel flickers a bit at half the screen's refresh rate, but half the pixels are 180 degrees out of phase with the other half, so it hopefully all works out and isn't noticeable on average content. If your monitor has bad flicker in the first place and you use it to d...
