but at least u cud get a rough fps measure right?
i mean heck, i thought splinter cell conviction would lag like hell but i actually got 30 fps when i played it
A "rough measurement" that isn't representative of any specific game and therefore mostly useless in determining the performance you can expect from anything else. If you look at graphics cards round-ups, how well game performance scales with GPUs' hypothetical performance varies considerably. In most cases, you cannot use any game to predict another game's performance with any accuracy beyond if a GPU struggles on a game that is generally considered lighter-weight, then it will struggle on everything else and conversely, a GPU that can handle the most demanding titles and settings will breeze through anything else. Anything in-between will be a mixed bag.
As for 30fps in Splinter Cell, if you can live with that, good for you. However, there is no shortage of people on THG who will tell you they consider 30fps as either unbearably low or marginally playable.
