Windows 10 Pro 20H2 Photoshop: CC2020 or CC2021, Performance preference below * Let Photoshop Use 70% RAM. * Use Graphics Processor, checked. * History & Cache Optimize: Huge Pixel Dimensions
I tryed these hardware below and the same issue CPU: i5-8600 or i5-9600 or E5-1650v3 RAM: 16GB or 32GB or 48GB or 64GB GPU: Quadro P620 or Quadro M2000 or RTX 2070s
[Issue reproduce steps:] New a blank file, Width 25000 pixels, Heigh 7500 pixels, Resolution 72 pixels. Use mouse to draw some lines (fast and nonstop), observe the line how close to the mouse. (default type brush)
1. Brush size: 50 pixles, good reaction. 2. clean artboard. 3. Brush size: 100 pixels, good reaction. 4. clean artboard. 5. Brush size: 500 pixels, good reaction. 6. clean reaction. 7. Brush size: 1000 pixels, a little lag. 8. clean artboard. 9. Brush size: 2000 pixels, very lag.
Check the Windows task manager when reproduce steps. I found only one CPU core is full loading (multicore CPU view in perfomance Tab), but GPU is idle.
[Question:] Why use so big brush? [Anser:] I am not the user, he told me big brush is useful for big range draw like weather.
Maybe CPU upgrade can get some help (Example: Intel 10th gen i9 level CPU) , but i think it is not a good solution
Any other suggestion?
