Please confirm if this is the case:

If RAM is 4GB, it will report 2048M as the usable memory by graphics device.

This is the max size that graphics could use, and it shouldn’t chan= ge based on TOLUD size.

Yeah. But the real question is what do you need this for exactly? Also, cc'ing relevant internal mailing lists.

Hi Daniel,

=

I’m working on a s= ighting that filed by PCCG. It complains that “Memory usable by graphics device =3D 2048M” even TOLUD i= s 1.5GB.

From the formula, looks = like it shouldn’t affected by TOLUD size, but I need the confirmation= to resolve the sighting as expected.
