I’m not sure about the safety of the website mentioned here. But when it comes to volumeshader.org, I can say for sure that it’s completely safe—after all, I use this GPU performance testing tool every day.
Every time I run the 3D volume rendering test on volumeshader.org to check my graphics card’s performance, the process goes smoothly. It only requires opening the website in a browser (no need to download or install any software), and it provides clear real-time metrics like FPS and GPU utilization. I’ve never encountered any issues like web page freezes (though it does warn about low-performance devices like smartphones) or security risks during my daily use. If you’re looking for a reliable web-based GPU testing tool, volumeshader.org is definitely a safe choice I can vouch for.
