Once we have high level agreement on the structure needed around these optimizations there is definitely more that can probably be optimized using SSE in the RemoteFX code, and I should be able to keep working on it.

Well that might work if the change was big enough to be easily visible. On my test system (see above) I actually haven't been able to tell any real difference between any of the optimizations that have been made so far. That includes all the memory allocation work that was done the other day as well. I also want to try a second version of the SSE method that I already wrote (using integer logic instead of floats). Without being able to see subtle differences I won't know which one actually performs better. There has to be an easy way to do this. I have used several different tools/techniques on the Windows side of the world in the past (most of my experience has been in the Windows world so far). I will keep thinking about it and looking for a solution. > It's easy to find ways to stress the implementation and see if it > works faster or slower.

My ideal goal would be to get smooth application refreshes (including dragging/scrolling/minimizing/maximizing windows) on a ~$100-$200 basic PC (think Intel Atom or AMD Zacate system) with a dual-monitor setup running at up to 1920x1200. A secondary goal for me would be smooth HD video running on at least one of the monitors. I have no idea if we will get there, but every little bit will help.
