I'm very excited about your project! These are the specs on my everyday machines:
Device 1 - PC
Processor - Intel Core i7-8700
RAM : 16GB
OS: Win 10
Browser: Chrome
Device 2 - Laptop
Processor - Intel Core i5-7500
RAM: 8GB
OS: Win 10
Browser: Chrome
Let me know if I can help in any way! Could try other browsers or a couple lower spec devices.
