windows 10 – Google Chrome unloads discrete GPU memory – causes initial lag (around 1-2 seconds) when start scrolling

Ever since I switched chrome graphics settings to gtx1060 from Intel HD 630 on my laptop (in nvidia control panel) I had this lag when trying to scroll page after around 30 seconds of idling.

Win10 task manager shows that lag happens after gpu unloads memory (only chrome is running on discrete gpu). When I start scrolling gpu takes a couple of seconds to start using vram (around 0.1~0.2GB) and only then unfreezes.

Disabling everything in chrome://flags didn’t help.

Turning on high-performance in windows settings didn’t help either.

Running on integrated graphics helps, but it’s a worse option (for a laptop that always works on AC plug).

NVidia driver: 445.87

Here’s my chrome://gpu features:

Windows 10 – external display lag on an extended laptop

When I connect an external display to my laptop and extend my desktop, the external display will have a horrible update rate, to the point where I can't watch a movie or the like because it becomes choppy.

The thing is, it only happens when I choose to expand my desk.
If I clone my desktop, the external monitor and the built-in monitor work perfectly.

I thought it might be the 4k resolution of my TV, compared to the 1080p resolution of my built-in, but if I go to super resolution and I set my built-in to 4k, the external monitor still works perfectly when It is cloned, but just as horrible when running expanded.

I have tried with 2 different TVs
I tried with 3 different HDMI cables (2 passive, 1 active)

My laptop is a Lenovo Legion y530

Anyone have any idea what is causing this?

ssh – Input lag sshing to raspberry pi 3b while its running docker

On my raspberry 3B, ssh from another PC is working fine until I start a docker image. Currently, I have portrain, pihole and nextcloud containers on the Pi, but the problem arises no matter which container I start running. Then there is up to 3 seconds of random offset when I type commands using ssh directly on the Pi (host). The problem goes away as soon as I stop the containers.

– Raspberry Pi 3B running the latest Raspbian
– Raspberry connected via Ethernet
– Docker using bridge mode for the network
– Terminal directly on the host which works well.
– The connection is fast. Only inside typing delays of the ssh environment

usb on the go – Super slow file transfer via OTG and Android 9 system lag

So I am using a new Lenovo TB-8505X with Android 9 and I have tried several file managers and always when I try to transfer files to one of my USB sticks, the speed is too slow, like a MB and gets even slower and the system starts to lag, when the transfer is complete, the system resumes normal work! At first, it starts to transfer quickly, like instantly 10 to 20% of the file, then it slows down!

On my old Lenovo Tab Essentials with Android 5, everything transfers quickly and the system does not drag! Why this and what can we do about it?

I have already tried to enable USB debugging and all that, to no avail!

Does any of you have this problem, seems to be a pie problem …

Is it even solvable?

The device works perfectly except for this one problem!

P.S. Doesn't that seem like a warranty issue or not?

Lag caused by the last Roblox client update

I received an update from the roblox client on 3/12 and I noticed a serious lag in input and rendering on games that otherwise had not had the problem before updating. The frame rate goes from 60 to 12 when you do nothing. Even at the lowest settings, roblox is late, I am broadcasting but it was not a problem before the update as I was able to stream at 720p 60fps and play roblox with the highest manual graphics without a single problem. Even when I broadcast, neither my GPU nor my processor is used more than 50% and this problem persists.

I have tried:

  • rotate graphics fully
  • force GPU rendering in nvidia and windows graphics settings

My specifications are:
AMD Ryzen 5 2600 @ 4Ghz
GTX 750 TI

I don't know where to post this, but I haven't heard from roblox after emailing them two days ago and I can't post in the roblox devforum. If someone could shed light on the situation, I would greatly appreciate it!

How to control an Android phone with the mouse and keyboard of a laptop without lag?

I have tried a software called "MyPhoneExplorer" which has a mirroring function and using it via Wifi gives a mouse input offset. It may be possible to achieve this without lag, such as by using a standard Bluetooth mouse connected to the phone. Maybe somehow connect the PC to the phone via Bluetooth?

macbook pro – Extreme lag when opening folders, new tabs, drag / minimize windows. and clicking on any text box

When I use the Finder, every time I open or close a folder, even if it only contains a single text file, my computer freezes completely for 30 seconds to a minute . Also, every time I click the green button to cancel the full screen of a full screen application, my computer is 5-10 minutes late, and starts again if I try to drag the # 39; s application. The computer is also one minute late when closing an application.
A possibly related problem is a less extreme lag when you click on a text field, whether in a Chrome browser or part of the operating system. Even clicking on the title and body sections when you ask this question induces 15 seconds of gel each. This text offset affects the login screen.
My computer can still run KSP and Minecraft easily, so I don't think it's a processor problem (although my computer lags behind if I click on a text field in these games).
In addition, the first tab, whether safari or chrome, that I open after midnight takes 5-10 minutes to open.
Restarting and resetting the PRAM has no effect.

focus – Reason for lag in lens / sensor and triode mount?

I've noticed that my Canon Powershot G11 tripod mount is no longer in the center of the camera body and is not aligned with the lens / sensor. Is there a reason for this? My concern is that when I rotate the camera on the horizontal axis, the lens / sensor is not the center of the imaginary circle. I can not accurately explain my concern, but the fact that the lens / sensor is not the focus, that the focus of the circle is off-side disturbs me.

lag – problem of delay in the creation of blocks (Godot)

We develop a game at Godot and get stuck when we try to split the map into pieces. Namely, the scene is a forest, where the spawn positions of trees were generated by the sound: as the trees are too numerous to be loaded, we created a Chunk knot, which only includes the trees that it contains, and which is instantiated and uninstalled depending on the player. position. Although this does not seem to be enough: whenever a new block needs to be instantiated, we get a lag spike. How can we improve that?
This is the script attached to Chunk:

extends Node2D

var noise

func _ready():

func LoadTrees():
    var x=-38
    while x<39:
        var y=-14
        while y<15:
            if noise.get_noise_2d(global_position.x+float(10*x),global_position.y+float(12*y))>0.07:

func _on_Exit_body_exited(body):

func _on_AreaLeft_body_entered(body):
        var NewChunkPos=global_position-2*Vector2(380,0)

func _on_AreaRight_body_entered(body):
        var NewChunkPos=global_position+2*Vector2(380,0)

func _on_AreaDown_body_entered(body):
        var NewChunkPos=global_position+2*Vector2(0,170)

func _on_AreaUp_body_entered(body):
        var NewChunkPos=global_position-2*Vector2(0,170)

The functions that the script calls from its parent's script are as follows:

func InstanceTree(pos,Parent):
    var tree=Tree.instance()

func InstanceChunk(NewChunkPos):
    if not self.has_node(str(NewChunkPos)):
        var NewChunk=Chunk.instance()
