Bush Lag Worsens When Zoomed In

    Alan, Regarding Brian's comment above. I am using the Nvida studio driver and not the Game Ready driver. Don't know if that will have a big impact. Regarding RAM, I just ran a bit of a test and here's what I see. ( note you will see I am running a 3060Ti now. I only switched from the 2020 because I put it in a computer I just built for my wife ) Basically, Brian is correct the GPU does most of the heavy lifting when masking but it seems like the RAM isn't really what's coming into play with masking. 

    I did some masking on the bottom layer of a 2 layer image with 7 filters and the Dynamic contrast filter is one of them. What I see happen in the Windows resource meter is CPU utilization increases from around 2% to about 8% and the GPU utilization increases from 0 to about 13%. You will see in the screen shot below that the 3D processor on the GPU is the thing that comes into play. Neither the the system ram or the GPU ram usage increases much.

    Have you tried lowering the Video Card Strength? That has helped me in the past when I had lagging brushing.

    Also, the layer (Effects or Local Adjustment layers, not an additional image Layer) can have an effect when you are working on one lower in the stack. All the layers above the one you are masking have to be re-rendered as you brush your mask. Having a Dynamic Contrast layer in the stack can affect it as it is particularly GPU intensive and the GPU is also used to track the brush strokes. Turning off unneeded Effects while brushing can help.

    Brian Lawson Thanks for the suggestions. I first tried cutting the Video Card Strength in half. No improvement in brush-lagging at 100% view. Then I moved the Local Adjustment layer I had been editing from the bottom of the stack to the top by drag-and-dropping it, plus I turned off the three other adjustment layers. Again, no improvement at 100% view.

    Lastly, I went to fit-to-screen view (about 46%). The brush-lagging improved a lot, resulting in a tolerably slight lag. However, reducing the magnification of the image while brushing is not always desirable, such as in the photo I'm currently editing.

    I meant to mention that I also exit, then restart On1 PR when it is lagging like this, hoping that would help, but in this case, it does not. Is there anything else I might try?

    Edited to correct myself - Alan, If you saw this comment in your email - never mind - actually you want Fast Preview on which is how you have it set.

    Thanks David Kick. Not sure what to try next. Sometimes you've got to zoom in to do some detailed brushing.

    Is more motherboard RAM likely to help? I'm at 16GB now.

    A more powerful video card would probably be a better solution. The GPU is used to track the brush movement so the faster it is the less lag there will be.

    Thanks for that insight. Yikes, I would not have thought that a now-3-year-old graphics card with 8GB VRAM (Nvidia GeForce RTX 2060 Super) is too slow. I thought I was buying a graphics speed demon at the time!

    Are you thinking an M1 Mac with integrated video would be faster?

    All I can say is I don't suffer from brush lag on my M1. It is possible that more VRAM on the graphics card would help. You should ask tech support about that.

    That RTX 2060 Super should be more than enough to run PR. I was using an RTX 2060 Founders Edition and didn't have any issues with masking and brushing. Just curious are you running a high refresh rate 4K monitor that can place a high demand on the graphics card. How long has it been since you did a clean windows install? I am convinced I saw much better performance after doing one. That said a clean Windows install also means a clean install of the Nvidia drivers perhaps you could try that. I would suggest doing a search for DDU clean install and you will get plenty of instructions on how to do it. 

    My system specs:

    Monitor: BenQ SW2700 27" QHD 1440 IPS

    CPU: Intel I5-11600K CPU @ 3.7 GHz
    Motherboard: Gigabyte Z590 AORUS Elite AX - WiFi 
    RAM: 32 GB Corsair Vengeance LPX DDR4 RAM
               3000MHz running at 3200 Mhz
    GPU: GeForce RTX 2060 - 6GB RAM
            
    Power Supply: EVGA Super NOVA 850 G+ 
    OS: Windows 11 Pro 64 bit

    Drive Configuration:
    OS and On1 on Primary internal Nvme drive
    ON1 Scratch and browse folders on 2nd internal SSD
    Photos stored and edited on 3rd internal SSD

    David Kick I am running a UHD monitor at 3840 x 2160 resolution, 60hz refresh rate, Std Dynamic Range color space. I notice you have 32 GB of DDR4 RAM. Does On1 PR take any advantage of that? Brian Lawson notes above that the GPU (and presumably not the DDR4 RAM) tracks the brush movement.

    I did a clean reinstall of Windows 11 last month after I had trouble installing On1 PR 2022.5.

    Another thought that had occurred to me is that some video cards have 2 sets of drivers for different purposes. One is a higher performance set. David probably knows more about this than I. Have you looked to see if this is the case for your card and if so, have you tried both sets to see which works better?

    David and Alan, what are the pixel dimensions of the photos you are using for this discussion. Could there be a difference between the file sizes that is coming into play as well?

    Have you setup your Nvida control panel 3d settings. Note in the screen shot below it shows I have added On1 to the programs tab and set it to my graphics card and set power management to prefer maximum performance.

    Brian I am editing 42mb file from my 5DIV pixel dimension 6720x4480

    Brian Lawson David Kick Like David, I am using the Nvidia Studio Driver, which Nvidia seems to recommend for photo editing. I haven't compared it to their Game Ready Driver but can do that. David, I did not have my NVidia settings matching what you've set your video card to, and have matched your settings. Will try On1 again and let you know if that has any positive effect. Brian, I am currently editing a 27MB photo that is 6048 x 4024 pixels.

    Just tried editing the same photo with the Nvidia control panel settings suggested by David Kick. It seems to speed up brush performance quite a bit! It's not perfect, and I had to wait for things to catch up, but it definitely does better now, especially with other Local adjustments turned off as suggested by Brian Lawson.

    Thanks to you both for your help!

    Alan

    Glad your seeing some improvement.
