I found that when the core clock was at lower 2D clocks (<~500Mhz on my OCed 290) the game would being to behave oddly, running slow, then fast for a moment, then slow again, repeating the cycle roughly once per second. Even at 2D speeds though, the GPU should be more than capable of handling it. Opening up youtube in the background (which due to some glitch or another, causes the cores to spin up to 3D speeds) allowed the game to run normally.

I wouldn't be surprised if this is all just an issue with AMD's beta drivers for the card (afaik, there are no WHQL certified drivers for it yet - current version is 13.11 beta 9.2), but if anyone is encountering this, thats the solution I found, and it might still be worth investigating.

Some more testing has confirmed that as long as I have an mp4 or flv playing at 2x speed, it will trigger the GPU to spin up to full 3D clocks with minimal load, which allows transcendence to function properly. Some videos will not trigger a full speedup to 3D clocks while playing at 1x speed. When the card is not running at 3D clocks the game begins to experience periodic lag & bursts. (And when I say periodic, I mean with a constant period of ~1s - as in, the mathematical definition of periodic)

Very strange. It sounds like a driver problem, but I'm wondering if there is anything that Transcendence is doing to make it think it doesn't need the extra clock-speed. Strange.

Hm, it seems to be specific to my system:
Sutaa has the exact same card, exact same CPU, some of my ram, same chipset, and while he notes that videos also spin up the clock speeds, transcendence plays just fine on his system (resolution 1600x900, 1 monitor)
I wonder if it has something to do with having 3 monitors (1080p,1080p,1280x1024). I will attempt to test on some other AMD systems I have.

I tried using the graphics debug option, but it was saying it was running constantly at ~28fps (of 30), which was clearly not true based on the visible rate from frame update
