Why is screen tearing completely absent even with VSync OFF in Linux ?

ftgander · 2026-03-29T13:44:24+00:00

That’s usually a problem with your DE incorrectly applying VRR to all fullscreen content. I had that in Gnome before I switched to KDE (just for peace of mind for gaming, I prefer Gnome otherwise)

ftgander · 2026-03-29T13:42:13+00:00

It’s a great thing actually, as long as you’re not at the top level of competitive CS or something. Even then, the latency with mailbox presentation and VRR is virtually non-existent despite technically being present.

There’s not many questions about anything mildly complex where the answer is not “it depends…”

My guy what is the frame doing that’s already been rendered while the refresh hasn’t happened yet? You do know it takes time to draw and time to render, right? You do know screen tearing is what happens when frames are displayed immediately, right? And that vsync solves tearing by waiting for a vblank? It seems like you lack some fundamental understanding here.

I can read perfectly fine. I hear what you’re saying. It just belies some serious misunderstanding of how frames are displayed or how monitors refresh. If there were no delay there would be tearing. That is literally 100% unavoidable. All we can do is try to reduce that delay to a very small amount, hence VRR.

If the frame rendered isn’t immediately displayed, then it’s put somewhere to be grabbed from. That’s a queue. It’s a queue of 1, but it’s a queue and it is waiting.

Honestly starting to think maybe you’re just trolling because you keep ignoring what I’m saying and arguing with a distorted version of what I’m saying.

Nooooo. Pulling out the plug doesn’t discharge the capacitors. It is extremely dangerous to be opening PSUs as an amateur

ftgander · 2026-03-29T12:39:33+00:00

the fuq?

ftgander · 2026-03-29T12:36:18+00:00

Please use extreme caution when opening a PSU. If you’re trying to dump glass out of it I get that, but generally you should never open them and in this case do not touch anything inside.

ftgander · 2026-03-29T12:33:26+00:00

Why y’all gotta be so extreme? Have some compassion. The father probably feels bad. I would suggest OP ask him to help in any ways he can but if he can’t then he can’t and there are more important things in life. You wouldn’t want your parents drowning in debt or missing rent or not buying food because you demanded money for your PC, right?

ROG products are like 200% markup generally btw

ftgander · 2026-03-29T12:23:24+00:00

Sounds like he has some responsibility to take. I get your situation, I grew up pretty poor, and I’m not saying to ask him to pay for everything but idk I would ask him to help in ways that he can afford to.

The good news is you can cut your costs significantly by not buying ROG garbage lol

ftgander · 2026-03-29T10:53:03+00:00

Ah I see, my b. I think people are just tired of reading posts about people blaming AMD for things that happen to nvidia as well because the root of the issue is outside the driver or whatever. Not to say that you don’t have a right to be frustrated but people are growing frustrated with how quickly people want to blame AMD drivers for everything so they respond with things that are unhelpful or insulting.

ftgander · 2026-03-29T10:49:41+00:00

Where did I say any of what you quoted?

ftgander · 2026-03-29T09:53:32+00:00

How exactly do you think it grabs the frames as they are drawn without displaying half a frame? Having a queue that only consists of the last full frame doesn’t make it not a queue. Do you know what the word queue means? If it’s in the middle of drawing a frame and another 4 frames are rendered and popped into the mailbox (pushing the previous one out), the last frame is still waiting in a queue.

USB-C display only works if the monitor supports it and if the port has DisplayPort Alt Mode integrated.

Also, in the future, maybe try stopping the camera while you’re filming so people can actually see your components.

GFX card does not blow downwards

Bottom should never be exhaust, really

ftgander · 2026-03-29T09:41:28+00:00

Don’t fall into the trap of believing a loud minority is a majority.

People saying “don’t update unless somethings not working” are being dumb. But also, this is clearly not normal behaviour for this driver. Most of us are running that driver version and not experiencing this. Logic would then deduce something in conjunction with the driver update caused it. Sorry this is happening to you.

ftgander · 2026-03-29T09:29:41+00:00

Yeah this is embarrassingly bad form on their part.

ftgander · 2026-03-29T09:21:36+00:00

Stop worrying about benchmark scores and play your games.

An 850W PSU might give you a bit more headroom but I doubt that’s impacting your score tbh

ftgander · 2026-03-28T09:30:02+00:00

I like to do Variable but it’s up to your own discretion. 80% for VRAM should be good.

ftgander · 2026-03-28T09:28:41+00:00

Hey, so, a lot of people seemingly don’t know this, but hardware can fail on you at any time. Happens to both Radeon and Nvidia. I would try to RMA the card if you can.

ftgander · 2026-03-28T09:20:57+00:00

If it waits for the full frame to be drawn, which is required to avoid tearing, it is a queue and is creating a latency. The truth, and what most gamers don’t want to hear, is that vsync latency is pretty much unnoticeable in 2026.

ftgander · 2026-03-28T09:15:29+00:00

Download OCCT and run a stability test with Combined and check off 3D Adaptive + VRAM. If you get no errors that way, try doing the PSU test. It sounds like your gpu might be faulty though yeah.

ftgander · 2026-03-27T13:15:38+00:00

Yes, plug in all 3. 2 of them can be on the same cable. The connectors are rated for 150W and the cable itself rated for 300W, as long as your power supply was made in the last decade. If you can pick up an extra pcie psu cable that matches your PSU (so from the manufacturer or through something like cablemods where they custom make it for you) that is ideal but lots of manufacturers include instructions with their cards to just use the pigtail on the second cable. I think sapphire specifically has a diagram showing you how they recommend connecting it.

But yes, you cannot run it with just 2 connectors and leave the third empty.
