When I activate Stellar in part design my CPU usage spikes to 100 percent and after approximately 5 seconds the program has to be restarted. Is there a quick fix for this or is the only way to buy a certified Quadro/RadeonPro GPU? 

My System specs:

• I5 8600K
• Radeon RX 7800XT
• 32 GB DDR4
• Samsung SSD 970 EVO 500 GB
