Hi, I'm trying to figure out why Reaper shows only 10% FX CPU use but maxes out Real Time CPU use. It doesn't matter how I change the buffer size or whether I use ASIO/WDM drivers, RT CPU is always maxed out. What is using all the CPU?

I have a AMD 6X 1090T CPU and 16GB RAM so it's a reasonably powerful PC.

Task Manager reports 16-20% cpu use when i play the project. I have the buffers set very high Reaper still breaks up and registers 100% Real Time CPU. This is really bizarre and frustrating.

Buffers: WDM 185ms
ASIO 2048 Samples
Wave Out 371ms

It doesn't matter what the buffer size is RT CPU is always 100%.
