For those having troubles with NTE on Retina displays
Choose a lower resolution preset in the OS, disable MetalFX in the game and pick a lower Rendering Accuracy value. I chose Default + 0.6 accuracy as it's basically 1080p (1764 x 1147) for my Mac and looks pretty good on a 13" display.
Managed to achieve solid 30fps on a modded base M4 Air at Cinematic with this.
