[B]Why doesn't your software use GPU computing? I have an i9-14900KF CPU, and it still feels laggy every time I paint. Meanwhile, my RTX 5070 Ti is sitting there completely useless—especially during watercolor simulation, my CPU hits 95% usage while the GPU barely scratches 5%, just loafing around doing nothing[/B]

You're right [USER=200080]@ShangGuanRuShi[/USER], Rebelle uses GPU only for RealShader, but not for painting nor for the simulation. The reason for this is mainly that developing algorithms for CPU is less restricted than for GPU and we need a lot of flaxibility during research and prototyping phase of developing new features for Rebelle. We want to implement GPU optimizations, but it's quite a large task and we need to finish higher priority tasks first. [USER=191369]@danglonghu[/USER], we sent you instructions for generating a backtrace file that could help us analyzing the crash. When you have time, could you please follow those steps?

[USER=170]@Michal Escape Motions[/USER] Thanks for the info. Some of us like to hear about the behind-the-scenes for Rebelle. Keep up the comments whenever possible. (From one Michael to another ;))

每次我在 8.33 版本中使用水彩笔刷时，应用程序都会崩溃，导致我的电脑完全死机，只能重启。我的电脑运行的是 Windows 10 系统，配备 16GB 内存。在 7 版本中一切正常。我在使用软件时已禁用 NanoZoom 功能。请问您能否调查一下水彩笔刷的这个问题？
