| | Video Ram cut in half? OK, so I have a BFG Geforce 9800 GT OC 1GB GDDR3 card. Now, onboard video memory is 1024MB, obviously. However, whenever I do dxdiag, it tells me that I have "Approx. Total Memory: 494 MB". What the hell? That's less than half of what I actually have. I didn't actually notice this until today, when I went to play Prototype on my PC for the first time, and it wouldn't let me set my resolution to anything above 1024x768. According to Prototypes read me, the resolutions are locked at certain levels. Quote: Cards with less than 512 MB cannot access resolutions with widths of greater than 1280 or heights of 720. This means with a card of LESS THAN 512MB VRAM has these available: 640 x 480 800 x 480 800 x 600 1024 x 768 1152 x 720 1152 x 864 1280 x 720 1280 x 800 Cards with less than 1024 MB cannot access resolutions with widths of greater than 1600 or heights of 1080. This means with a card of LESS THAN 1024MB VRAM has these available: The following are only available for cards with 512MB VRAM or more: 1280 x 1024 1440 x 900 1600 x 1200 1680 x 1050 1920 x 1080 1920 x 1200 2048 x 1152 2048 x 1536 2560 x 1600 |

| | What does it say when you access the advanced properties for the card? (right-click desktop -> Screen Resolution -> Advanced settings Is it 1GB dedicated VRAM or shared? |

| | LOL ur card is a genuine 1 GB card... but dxdiag only sees less than 1/2 of it... The reason I said lol is coz my GC's RAM is 256MB but dxdiag sees 510 MB on that control panel windows sees 256 MB if im not mistaken.. You should try updating your graphic drivers..

| | Yeah, I have tried reinstalling the drivers with a few different sets of Geforce drivers, including the latest WDDM 1.1 drivers. It hasn't helped. Everyone I've talked to, their dxdiag shows more VRAM than they actually have. Mine seems to be a very odd and uncommon problem.  Edit: Woohoo!!! I just installed the 190.15 drivers, and got a whopping 1MB of VRAM back!  Weird. I started playing Prototype today, and went in to see if I could change the resolution. I can get up to 1440x900 now. I have no idea what's going on... Last edited by blackroseMD1; 16 Jun 2009 at 07:14 PM.. |

| | Regarding the allowed resolution - Happy to see that was resolved in driver updates. Regarding VRAM: Not everything is memory mapped. I do not see an issue here. |

| | Eh, I called BFG tech support, and they had no idea what was going on either. Whatever, as long as I get decent framerates on my games, I'm not to worried.
