Hi Alex,running at 1600x1200 takes up to 2.44 times more pixels to "push" to the screen that 1024x768. This is a lot.Here is a link to some benchmarks at different resolutions for a game. It is clear that not only for some cards (even recent like the 9600PRO), above 1024x768 performance suffers, but also, it looks like these cards are not desgned to run at same perf above 1024x768.Although 1600x1200 is better for the resolution, on Radeons the Full Scene Anti aliasing comes for free up to 4x at 1024x768 (i.e. no FPS difference with or without - almost). Running at 1024x768 but with FSAA 4x could achieve almost as good visuals as 1600x1200 in most cases.http://www.firingsquad.com/hardware/call_o...y_ati/page4.aspHope this helps!

Hi Jean-Luc,I have a ATI RAdeon 9800 Pro 256 Mb and the link to the benchmarks you posted was very helpful. I didn't realise how many frames I was losing running at 1600x1200x32 at 4AA and 8AF.Also the idea of a your wonderful gauges running on networked PC's would be VERY exciting :-) . Anyway we can bribe you to do this :-)Thanks for your great contributions to the flightsim community.

Too dumb to see the problem (or just plain lucky)!Running a Ti4600 with a ViewSonic 21" Pro Series P815 #1 PrimaryRunning a 21" Samsung SyncMaster 1100P on the 2nd output of the Ti4600Running a 17" Vivitron as my third monitor on my sencondary Video card which is a Diamond Stealth III S540 PCI card.I usually run the main panel on #1, secondary panels on #2 of goodness knows what, and FSNAV on #3. In either windowed or full screen modes, I have seen no significant difference with the three monitors over two on the Ti4600, or single monitor use for that matter.I presently am useing a P4 3.2, 1G 400 Mem. but saw no tripple monitor difference on my previous AMD 1.2.Good Luck:RTH

JeanLuc,that is the funny thing. It seems I only gain very very little back when I go with a different resolutions or go from 8xAF to 4xAF. Strangely enough not everyone seems to have the problem. It might be also be mainboard specific.Anyway I did a lot of testing tonight, and I have decided to make the major change. I am going the project magenta road. They have a new GA panel with movable gauges that can be run from a networked machine. I tried the demo and it is very good. You can move and resize the gauges. It is running very smooth, a lot better than the FS instruments, comparable only to the Vector Technology from RealityXP. I will only use the basic primary flight instruments, so I still can have the engine instruments, the GNS530 and other plane specific stuff on the 2nd monitor running from the FS machine. That menas bye bye to plane specific HSIs, Jet Line and other stuff. But I pull a decent 25 fps running 1600x1200x32, AFx8 and AAx4 and all my addons like I was used to. I think the new "enhanced" multi monitor support will bring a lot of new customers to project magenta.I am a happy camper again.Alex
