recent activities of WidevieW

At first, I must state my FS environment...
I got WideviewW for FSX and setup into my most rececnt couple of PCs. For the outside view, Vista 64bit Core2 E6700, 6GB, RAID 0, XFX Geforce8800GTX & Geforce9600GT physx and Matrox TH2G. Resolution is 5040x1050.
And WinXP 32bit, Athlon MP 2xCPU, 4GB, RAID 0, Nvidia FX5600, 1680x1050 & 1280 x 1024 dual LCD for the cockpit view.
I also using MCP Combo panel.
I tried to use FSX for both side but even hide all cockpit view from Vista machine, FSX perormance was not accepable.
Therefore I downgraded FS to FS2004 for outside view to get much improved performance. It can over 30FPS but problem was there are stutter on the ground. Of cource it was reduced by chosing smaller aircraft on the client(I call Vista machine as client from now on)PC but still I don't like that especially during taxiing slowly..

Then I decided to downgrade FS to FS2004 for the server side too and got much improvement. Almost no stutter on the ground anymore. But problem is...I can't use newly purchased add-ons such like PMDG 747-400 etc...haha!
Today, I could fixed all small issues with PSS A320 Professional + FS2004 + MCP Combo. So, now, I have to decide... do I have to buy WidevieW FS2004 ? ha.... and PMDG 747-400 for FS2004 would be the next.... terrible.
