I just ordered Full Canvas Jacket about 2 weeks ago. Haven't received it yet but I am anxiously awaiting it. I hope it doesn't bog my system down too much.
I currently have a Pentium IV, 2.4ghz system with 512 meg of ram, a Nvidia GeForce Mx 440 graphics card with 64 meg of ram and an 80 gig hardrive.
Playing Red Baron now with either WFP or Beery Super Patch and all the bells and whistles turned on (plus a glide wrapper), I get about 30 frames a second with the highest screen resolution. If it stays anywhere near there with Full Canvas Jacket installed, I'll be very happy!!
Once I get it and have it installed and working, I'll post back to let you know how it runs on my system!
