Yes, DRI_PRIME GPU offloading works on G505S - and actually I think it's the only possible way of using a discrete GPU on this coreboot'ed laptop at the moment. However, it's usefulness really depends on your software and how fast is the integrated GPU's RAM: you may have 1600MHz CL9 RAM modules installed, while a discrete GPU's own soldered chips are i.e. 1333MHz CL9 only. I recommend testing them side by side in all the programs you care about and remember which one is better in what cases. > > Could here be an option created to enable/disable the dGPU at boot time > without recompiling? > If there could be a real benefit from doing so (does it consume less power if you "hide it" from your system by disabling a PCI bus?), such a way could be implemented - however, I don't know how to do it without using NVRAM (which I would like to avoid for various reasons) _______________________________________________ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-le...@coreboot.org
