Extremely difficult to render with newer beta versions & Basic Mogrts. GPU, RAM and CPU maxed out.

Hi @Reem29254214ad3p - You are running into a GPU effects error would you be able to send your project file to jamiec@adobe.com so that we can help you troubleshoot.  This generally means that you have two effects on a clip and you need to nest one of your effects and then apply the other effect to the nest.
