1. you cant increase dedicated video ram 2. the only way to get more video ram is by buying a better card...
the amd HD 7770 can easily play skyrim on like high to ultra settings at 1920x1080 :/ you wont be able to run very many graphic mods though.
Your specs didn't show. It went straight to "Can I run it" But no, you can't. Also it is ODD that XP 32 bit with 2 GB RAM and a 512MB card will work, But you need Windows 7 64 bit (NO32bit) and 4GB RAM &a 2GB card
- Turn of some graphic settings on your graphics software and/or in the game's settings. - You can go into the bios and give your graphics card some of your ram (going to be shared ram, not as good/fast as dedicated video ram).
