I've recently been running Civ 5 on my macbook pro, and have experienced a low frame rate only when there are many, many units in play. When beginning a new game, there are few units in play, and the frame rate is not noticeable. (I have not attempted to quantify the frame rate.)
My suspicion is that this reflects a heavier load on the memory to track all those units. Can you confirm or reject this hypothesis? Does the presence of more units in a game like Civ increase the load on the GPU?
Thanks for your response. That's what I was afraid of - there's basically no way to upgrade the GPU. It's the first time I've seen this computer struggle with any task, so I was curious about what was happening. I guess the GPU gets loaded by having to process animations for all those little units.
Luckily, Civ has an animation-free mode, although the aesthetics of the game are a big part of its appeal.
macbook.... the laptop? im not sure if you can upgrade those, laptops generally cant upgrade GPU's because they are soldered into the motherboard....so its a bust upgrading the gpu to alleviate this issue
Your GPU is bottlenecking the game beacuse of it's memory,as "Raiddinn" said it could cause trouble even in 10 years old game and that's right and you can't also upgrrade GPU as "FlintIronStagg" said and that's strange that you don't have option to change the res,I've this game before it worked fine on mine,no lags,no freezes,nothing.....strange
