You are describing a practical monopoly, but thanks! biggrin.gif

well i thought i described the difference between g-sync scalers and the various scalers amd has to deal. if you care to read it different, be my guest.

so you overlooked the differences in hardware and you completely missed it's that its one alpha driver on one laptop and no one knows how well it works?

but you will make a sweeping generalization. yeah right.

I did not overlook anything, the leaked driver shows they're working on it and I made no claims about how well it works.Again, that which makes it possible for mobile gsync to work(sought of) is that which makes desktop adaptive sync vrr.possible.It is essentially the same tech.

They could even make and sell the G-Sync adapters (they do) to recover costs. Oh well, at least PhysX and 3D are super prolific.

How they get better performance is by proprietary hardware. Why is this so hard to accept?

Nope, unlike most people on this forum, I don't run 4 graphics cards and MSI afterburner permanently installed so I have 0 chop with vsync disabled. It looks completely identical to having vsync on even though it's turned off. And no, my display isn't doing some crazy buffering thing because it looks the same on Samsung 245bw, Samsung P2770, and Korean IPS with no scaler. In the last 10 years, I haven't had noticeable vsync chop on any machine except for the following 7 situations:


1) Running mouse settings where the slider wasn't in the middle, meaning a setting other than 6/11 cursor speed. I use 800 DPI 6/11 1000hz.. If I run something like 3/11 cursor speed and 3100 DPI, chop can become noticeable when panning, but it's invisible at 6/11.

2) Running mouse polling rate under 500hz

3) Using a core 2 duo on a biostar motherboard, changed to an ASUS P965 and vsync chop disappeared

4) Gigabyte UD5H F7 BIOS had 0 chop while gaming, then I upgraded to F8 BIOS and suddenly have chop. F7 and F14 however both have no chop.

5) Running Torchlight 2 on Linux and has lots of vsync chop while the same game on Windows had 0 chop

6) If I plug in a 1000hz keyboard, vsync chop can start to become noticeable in certain situations. If I run a 1000hz mouse and a 125hz keyboard I don't get any. USB controllers can't handle two 1000hz polling devices at once.

7) Using a prerender (flipque) setting other than 0 or 1

Gsync and freesync are only useful for people who don't now how to configure a computer or who run a bunch of shovelware like MSI afterburner and virus scanners that are going to cause hiccups.

Without syncing there will always be some degree of tearing, even using a frame rate limiter.

I know what tearing looks like. I've used computers since the DOS days. It's not visible to the human eye on a properly configured PC with 2 DPC latency and 0 programs in program manager except Nvidia driver along with HPET off, Win defender off, and other relevant settings.

It also depends on hardware and driver in use as well. I can for instance achieve 0 tearing on Metro 2033 with a 970 GTX on Win 8.1 and 344.16 driver, yet I can't get 0 tearing with a 260 GTX on the same PC in that particular game, even when lowering settings to achieve same frame rate. The 260 GTX will look identical to the 970 in something like Borderlands though with 0 tearing whatsoever.

None of that has jack-all to do with tearing. If you aren't synced to the display, then your display is tearing. Period dot. You may not be sensitive to it, but it's there.

Neither DPC latency, nor the underlying causes of it, have much to do with tearing. There is simply no way to consistently line up each new frame with the vertical scan without vertical sync. I can see some tearing in almost anything, but it bothers me a lot less than the latency vsync tends to introduce, so I don't normally use vsync in anything remotely fast paced.

I believe the amount of tearing you are seeing is below your perception, but that doesn't mean other people wouldn't notice some degree of tearing, or find syncing useful, in the same situation.

Guess I have to repeat what I already said. The tearing is not visible to the human eye on a properly configured PC. You can get unlucky and have a badly made BIOS, drivers, or other hardware components and be stuck with it though. For instance, I have a lot of PC hardware sitting around and was running Crysis 2 once and had some chop in that game while panning. I unplugged the G400 mouse and plugged in a G9x laser (yes the G9x is technically worse for accuracy) and the tearing while panning went away to the point where it looks like vsync is turned on but it's off.

Both mice were set to 800 DPI 1000hz, yet the G400 caused tearing while panning while the G9x didn't. Game engines are strange like that.
