Talk:Terraria

After spending 50 hours in terraria on a Macbook Pro M1 (2020), I can say with no doubt the game does not run perfect. In the early stages it does seem to run very well, but fighting the Eater of Worlds drops the frames to barely playable, using Summoner Whips destroys the performance, The Destroyer (Mechanical Eater of Worlds) also drops the fps. Using a Summoner Whip on any of these bosses causes the game to run in slow motion even with FrameSkip ON. After gathering all the npc on the world, the performance also drops. Using a battle potion, causing more enemies to spawn also drops fps.

In short, if there are effects (like sparks from the Durendal Whip), lots of enemies or NPC's (Eater of Worlds or Destroyer "segments" count too) the performance tanks.

It is a bit better if not using the summoner class. But after testing it with Mage and Ranged classes, after acquiring late-game armour and weapons which have flame effects, afterimage effects etc. it gets to the same poor performance level.

I can concur. One thing that absolutely tanks the frame rate is maximum summoner gear. Stardust armor set, all three of the summon boosting accessories, and a Stardust Dragon rod, the frame rate dips as low as about 10fps.

And I verified with iStat Menus that the GPU is barely hitting 75% on my 8 core GPU Mac mini, while the game is absolutely pegged at 100% of a CPU core, and doesn't really take advantage of multiple cores to improve performance.

So even a fully loaded M1 Ultra Mac Studio would not really improve the situation for this game, at all. Really, the only thing that ReLogic can do is try to port the game to Apple Silicon native, which should fix things significantly, at least.
