for some with this issue it will be just that, get a new computer how some expected to play this game with an old pc is beyond me. for others there is a genuine issue.
for me, i change settings and my fps actually got worse, so back to high for me as it was actually better than it was at med/low. kind of weird scenario i know.
so high across the board 55+ fps with natural drops to 30 in wvw time to upgrade my graphics card i think:(
Anet are most likely trying to work who actually has a problem over those that just need to be realistic with thier expectations.
upgrading to an ssd would be nice and the prices are only set to keep coming down as the technology matures, they are not unreliable and last for 5+ years longer if you set them up right from the start.
10k rpm mech drives are far to expencive and you would be better off with an ssd as they are frankly far far cheaper.
load times are the only thing that will change though regardless of which storage medium you choose to go with.
upgrading to a 64bit os should be your first port of call, you have more ram than your system can use, download the iso from ‘my digital life’ they offer direct links that work just fine burn to an iso using nero or some other software, plenty of free ones out there cdburnerxp being one that does iso’s use your current licence as it should work on a 64 bit version of the same os, make sure you download the same os windows 7 ultimate or the licence key won’t work. they may ask you to call to input a code, follow the instructions it’s really simple and hassle free and all automated.
graphics card, is fine for the purpose but it wasn’t meant for high performance in gaming, upgrading that opens a whole different issue with power supply changes.
