Final badge may not have quite this performance, but we fixed hardware acceleration on the I2C bus for the OLED and measured 340 FPS animating a stick figure. The animation is simply flipping through 20 or so monochrome bitmaps so there's nothing special or particularly computational complex. Nonetheless, it is ridiculously fast!

The plan is still move the OLED to the SPI bus and share with RFM69 and flash storage, the cheapo Ebay screen we got off Ebay came I2C. SPI OLEDs are in the mail.
