Photoshop lagging on a new laptop with i7

Hi everyone,

I have just bought a new laptop, a Lenovo Yoga 920, i7-8550U, intel UHD 620, 4k screen, 16gb of Ram and 1Tb SSD. Installed a trial version of Photoshop CC 2018 and the lag is just terrible, mostly visible when drawing with my pen.

I'm using PS CC 2018 at my work with a fairly old PC with an intel i7 4770, 16gb of ram and etc. and everything works perfectly. What pisses me off is that the desktop PC is benchmarking lower than this laptop and everything is super smooth.

I tried to get the GPU to basic settings in PS and that helped a great deal, but it's still not smooth using even basic brushes. With GPU turned off the brush is perfectly smooth but the canvas scrolling is so choppy and slow that it is just unusable. PS CC 2017 is performing a bit better but not much noticeable.

Looking at my resource monitor while using the brush, even at advanced settings while lagging really hard the GPU is utilized at just about 60%, and CPU maybe at 25%. I tried to play around with other settings but nothing really helped.

Laptop is at the best performance power mode, tried also with 1080p resolution with almost no difference, all the latest drivers, tried older drivers... I think I'm going crazy at this point.

Just as a comparison Affinity Photo is working smooth as it can get, no lag at all.

I have also tried to reset my laptop to factory settings just to be sure, but with no success.

Does anyone have an idea what could this be?

Hey guys, seems that your laptop specs are more than enough for Photoshop requirements, did you optimized the settings following this guide Optimize performance Photoshop CC ? Also, plugging in the charger would help performance if you didn't try. Another thing could be that Photoshop lags, freezes, or runs slowly . Usually is normal that there's lag with brush tool on big canvas, being Photoshop using raster images!

I returned the surface book 2 also, it made no sense to keep that machine not being able to use it for work. I went through I guess every possible step, I spent a few hours with adobe support, no solution was found.

Laptop plugged in, maximum performance settings, nvidia drivers optimized for performance, nothing helped. I know it’s not a normal behavior because I have a desktop with an i7 4770 and a gtx760 and it works flawlessly, and those specs are considerably worse than the SB2. Same conditions on a i7 8650U and a 6gb gtx1060 and even the basic brushes are not keeping up with the pen. It had the same performance as the yoga 920 with integrated graphics, and that thing should also be smooth with a basic brush and a clean canvas.

And yes, I checked, photoshop was using the nvidia card. The problem is both the cpu and the gpu are chilling under 20% while the desktop machine is running to 100% without a problem on heavy brushes. I guess there is some bug either in windows or photoshop that makes these laptops unusable in photoshop. Also both laptops experienced choppy animations in windows ui. I don’t know if these problems are connected, but something odd is going on.

For example other gpu dependent software was using the gpu absolutely normally to 100% and affinity photo had terrific performance.

Has there been a definitive answer to this problem? I have the very same issue. Brand new system, 32GB RAM, Nvidia GeForce GT 1030, Intel i7 and using all the 'correct' Photoshop preferences and only SSD for OS, virtual RAM and image storage (and they are all different SSD cards.

My old (9years now!) desktop PC works more quickly than this brand new one! AND there have been no upgrade to that old PC!

So what is going on here? It is seriously laggy and particularly when warping and stuff like that. THe old PC, with exactly the same images works smoothly.

Guys you need to be very specific about the circumstances that lead to lag. There are too many situations that can cause things to slow down, so we need full information.

3000 pixels square should be absolutely no trouble, but is it definitely pixels and not inches? We see that several times a year.

Nor should a 25 pixel brush, but if the spacing is set to 1% that might be different.

But what sort of brush is it?

What are the smoothing settings?

If it is the Mixer brush, do you have Sample all Layers checked? (Try turning that off)

Do you have rulers turned on? Some people find that slows things down.

Are you using a tablet, and is performance similar with tablet and mouse?

Is your GPU using the best driver? (It should be loaded from the video card maker's site)

What are your Scratch file settings, and is there plenty of room on that drive? Check the root directory of your Scratch drive for Photoshop ### Temp files. How big are they? Are there any with old dates? Orphaned temp files can clog up the drive, and will never go away unless you delete them.

So try and think about the above points.

Give us specific information

Think about pasting a screen shot of your workspace with layers panel showing.

Open Photoshop and go Help > System Info > Copy and paste to this thread.

All these things can help others to help you.

I have exactly the same Problem with the Lenovo Yoga 920.
It´s horrible. Every review about the Laptop and the pen says it´s top notch, but I have the feeling that no one is really testing it with
an app besides the default Windows Ink app.
I´m also thinking of returning the laptop because there is no way to draw with such an enormous lag.

Just an update:

Thinking that the intel UHD 620 was underpowered I returned the laptop and bought a Surface Book 2 15" with the GTX1060, and there is still lag! The whole interface is choppy and the brush stroke is always rendered choppy instead of smooth. It doesn't make any difference if the graphics settings are Basic or Advanced, there is always that stuttering and choppynes. I'm really running out of ideas, when I drop the resolution to fullHD everything is super smooth, but on the native almost 4k res it's a mess. Other apps like Affinity photo and Leonardo are perfectly smooth while drawing.

Is there a setting that I'm missing? Two completely different laptops with fresh instalations of Photoshop having the same problem.

It feels like the UI is rendering at 20-30FPS

Tests on both PCs were with a 3000x2000px document and a general hard round brush at 25px. I noticed that the size of the document and the brush size had no effect until it got to ridiculous big numbers, like a 2500px brush etc.

And system info if it helps:
