My system specs are as follows:
Intel Core2Duo E6600 (2 x 2.4ghz)
2gb DDR2 Ram
ATi X1600SE (256mb onboard, 256mb shared RAM)
22" Samsung monitor (1680x1050, I run RS at 1280x800)
I get 30fps with reasonably low and fine tweaked settings.
The only reason why I think TS2012 won't run as well is the increased system requirements - unless the ones I have seen are the recommended ones ....
Should be fine to be honest.
I am running TS2012 (in legacy mode - I was one of the people that Darandio makes reference to as I initially couldn't play at all, but it has now been patched and I'm running it as before now pretty much) on a laptop with the following specs:
2GHz Intel Core 2 Duo T7200 (2 x 2 GHz)
2GB RAM
Intel® Graphics Media Accelerator 950 (up to 224MB shared RAM)
15.6" screen running 1680x1050
Usually run the game at 1280 x 1024
I do have to have things turned down pretty low and I don't the sort of frame rates you get in RS. Some of the add-ons are a bit hungry as well.
I do want to upgrade to a proper PC that can support it properly at some time in the future, but for now it does OK (and has done for 18 months
)
