So, I have figured out that I have to turn off my IGPU in order for RedM to load, however, I’ve been able to run RedM no problem in the past. This problem didn’t start until I last updated my computer. My game is set to run Directx 12, and I disabled my IGPU only to find out that my game would not run properly, nor would RedM. Drivers for both GPUs are up to date, and both my computer & game was set to pull from the dedicated GPU. It seems that my GPU just isn’t strong enough to run my games without the IGPU enabled. It’s sad and frustrating that I can’t enjoy RDO RP because of my IGPU.
