Trying to Box Rift

[Mystic]

My machine is sort of middle line performance, these days at least. Running an i5-2310 at 2.90 GHz, not OC, 64-bit Windows 7, 8GB RAM, and an ATI Radeon 5770, clocked to 950 MHz GPU clock and 1435 MHz memory clock.

I can run 5 clients and not tax out the system. Each client varies between 12 fps and 20 fps depending on how much has to be rendered.
I run each client at low, using the standard renderer (haven't needed to try the low qual renderer). It's certainly not optimal but it is playable.

I also have an old Dell XPS 420 (a quad core Q6600), with the same ATI Radeon 5770, and while it will run WoW five clients at high quality, it will NOT run 5xRift. I get about 1.3 fps max per client, and mostly the rendering lag is just too terrible and crashes out the clients.
