Back in the spring of this year, I thought it would be fun to make a thread to answer the question put to me about Macs and gaming - "can you run it on Ultra Settings?" http://forums.macrumors.com/threads/the-ultra-settings-thread.1974637/ While that was a cool little experiment, it didn't draw as many substantive replies as I'd hoped. Maybe this thread will. As gamers, we are sophisticated enough to know that games run at wildly varying performance levels, depending on how well your Mac meets or exceeds the requirements of a given game. Playing a modern game on max (or Ultra) settings means that it will usually look gorgeous. Usually, that is, unless your frame rate stutters, or worse, degrades into a slideshow. Pretty much all of us have had to make compromises to balance visual quality with smooth framerate. But, what if you went the other way with it, moving the needle from ultra settings and eye candy to performance and pure frame rate? What would it take to eke out the most frames per seconds in the same games that I tested in my Ultra Settings Thread? Here's what I've found out. (Once again, for reference, my mac is a late 2012 21.5" iMac with 2.9Ghz i5 CPU, 8GB RAM, and NVIDIA GeForce GT 650M 512 MB. My native resolution is 1920 x 1080). Borderlands 2 - Everything set to low or off, at 1024 x 576 (between 49 fps - in Sawtooth Cauldron and 120 fps - in Control Core Angel) Borderlands the Pre Sequel - Everything set to low or off, at 1024 x 576 (between 50 and 122 fps) Batman: Arkham City - Everything set to low or off, at 800 x 600 - 62 fps on the included benchmark Bioshock Infinite - Everything set to low or off, 72 fps in in outdoor combat areas at 1024 x 576 Counterstrike Global Offensive - Ultra @ 60 fps (no changes were needed to achieve 60 fps or greater) Dead Island - Everything set to low or off, 35 fps in outdoor combat areas at 1024 x 576 Half-Life 2 Update - Ultra @138 fps (no changes were needed to achieve 60 fps or greater) Left 4 Dead 2 - Ultra @ 85 fps (no changes were needed to achieve 60 fps or greater) Metro 2033 Redux - Everything set to low or off, at 1920 x 1080 in the Cursed mission - 45 fps Outlast - Everything set to low or off at 800 x 600 in basement generator mission - 62 fps Shadow Warrior - Everything set to low or off at 1024 x 576 - 65 fps in mission at Lo Wang’s home Star Wars The Force Unleashed - the game seems capped at 30 fps Team Fortress 2 - Ultra @ 93 fps (no changes were needed to achieve 60 fps or greater) Tomb Raider - Everything set to on or medium at 800 x 600, 59.4 fps on included benchmark Doom 3 - Ultra @ 60 fps (game seems capped at 60 fps) (no changes were needed to achieve 60 fps) I've added three games to this experiment that I didn't measure on the Ultra Settings Thread. Something for another time, I guess. Brainbread 2 - Everything set to on or high, 60 fps in Barracks map at 1920 x 1080 Paladins - Everything set to off or low, 48 fps at 1344 x 756 Red Crucible Firestorm - Everything set to on or high, 62 fps in outdoor combat areas of the Autobahn map at 1024 x 576 The following games I'm having to hold off on until I can decide whether or not I want to turn off SIP in Sierra to allow Count It to run. (If anyone has any insight for me to make that decision easier one way or another, please jump in): Rage Call of Duty 4. I don't think CoD4 will need much work to get to 60 fps, because it was already giving me 49 fps on Ultra/Max settings at 1920 x 1080. I hope that I've given you some food for thought. As with my other threads, please jump in to give us your performance numbers, including resolution, settings, (some like to include screen shots, and that's cool, too), and most importantly, your Mac's specs and Mac OS version. Please don't mix in Windows or Linux games in this thread, okay?
