This was with the Nvidia drivers installed? Generally, I'm torn on whether this power supply thing is a big deal. On the one hand, you're correct, you really need to burn the CPU and GPU to discharge the battery. It's not just gaming -- I've seen it when encoding video using Adobe Premier Pro...

So, just for kicks, I ran some tests using the Civilization VI built-in benchmark (my SB2 15 hasn't yet received the exploit firmware update, as far as I know). The results were interesting: 1080p medium graphics Best: 68 FPS Better: 69 FPS Recommended: 60 FPS 1080p ultra graphics Best: 60 FPS...

Well, whatever the impact, this is one where it's not going to be specific to the Surface line. Every machine, if properly patched, will experience the same, and so it comes down to how secure you want your systems to be. I have an older HP that my wife uses that I'm now thinking should be...

If you could do a test on Recommended as well, that would be helpful. That would tell us if there's a way to ramp down performance in the event someone doesn't want to hit the battery due to the power supply issue.

One question I have about using the Nvidia drivers is the impact on the power slider settings. Do the three settings still work or does that slider then only control the CPU?

In my own testing, I've found that there's a significantly greater difference between "Recommended" and "Better Performance" than between "Better Performance" and "Best Performance." That's fairly reproducible in both synthetic benchmarks (Geekbench 4 and 3DMark) and actual gaming. I've done...

What I don't understand, generally speaking, is why this would impact 2D and not 3D GPU operations. Certainly, 3D stresses memory at least as much as 2D, and I would think more so.

I don't have another 13.5-inch model to check out either. All I can say is that on mine, it's loud enough that I can hear it even when there's some background noise. If I'm in a very quiet space, then it's incredibly obnoxious. The 15-inch models I've used both have it like you describe -- you...

If you're checking when plugged in and the power slider is all the way to the right in Best Performance, then you might have won the coil whine lottery.

Incidentally, I'll add that from my initial research (prior to running my very informal tests), it appears that it's not Microsoft that's the problem here, it's Adobe. They're the ones who seem to be reluctant to support switchable graphics due to past issues, and this issue isn't unique to the...

All I did in my testing was use Premier Pro CC 2018 to encode a video after adding some simple transitions. I didn't actually do any editing (and in fact, that's not really my forte). When I encoded video, I could see the GTX 1060 in use, and if I switched the settings to software the GTX 1060...

I haven't received the firmware update on any of my machines yet. Once I do, I'll run the tests and report back.

This is definitely interesting -- that 2D graphics dropped so considerably. From everything I've been able to discern, that's not an expected result -- the issue that needs to be resolved is in the CPU and relates to accessing system memory. I'd say that if this were an SB2 it might make sense...

Just to be clear, pretty much anybody who spent top dollar on any notebook in the last 10 years is affected, and there's no word when Intel will be releasing new CPUs without the issue (it's architectural and so already baked into whatever's upcoming). And as the test shows that I just posted...

So, here's a test that was done comparing pre- and post-patch performance. It simply won't affect any of us here unless we use our SB2s for server-oriented tasks (there's only one specific benchmark, 4K read tests from an SSD, that shows a meaningful decrease in performance). Really don't think...

Right. Meltdown applies primarily to Intel CPUs and is both the easiest to exploit and the easiest to fix. Spectre is harder to exploit but also much harder to fix. The bottom line is that the impact of fixing the exploits likely won't matter directly to us end-users. Now, the impact in data...

I suggest reading some newer stories on this issue. First, it's not an Intel CPU issue, but rather a pair of exploits based on how all modern CPUs work. It applies to AMD and ARM processors as well. Second, the performance impact is actually negligible for most people. It's limited to some very...

I tried to replicate this on my SB2 15 using a few of the videos that came up on YouTube when I ran that search. I'm not seeing anything like you're describing here.

Regarding the first problem, I'm not seeing any issues on my SB2 15. Full-screen video performs as expected no matter the video source. I haven't noticed the second issue, but then again I haven't been looking for it. I'm very happy with how Netflix and Vudu video looks, but I can't say that...
