-norestrictions -- to be able to change the graphics settings
-noprecache -- to be able to start the game without the availablevidmem argument set
-availablevidmem 50 -- a multiplier to 'trick' the game into seeing 1339 MB of VRAM, yet it won't actually utilize it, this is my problem
-nomemrestrict -- trying to force to use all the availablevidmem, but doesn't seem to have any effect, this might be the culprit (or maybe it's referring to CPU RAM?)
-percentvidmem 1.0 OR 100 (doesn't make a difference) -- again, trying to force to utilize availablevidmem, doesn't seem to have any effect
