I run 20,1' Syncmaster LCD at its native resolution of 1600x1200x60Hz.It will not allow for setting higher frequency though.What are the best settings for ATI cards, so it does not take such a heavy performance penalty at this high resolution.I run it at AAx4 and AFx16 as someone once suggested as this seems to be the best solution for all ATI cards.ThanksDom

I have the 213T with a Radeon 9800 Pro running at 1600 x 1200 on the DVI connection. AMD A64 3500+ with 1gb ram.I have AA at 4x and AF at 8x and get a constant 22-25 fps (locked at 25) even with PMDG 737 Dreamfleet A36 etc. I use sparse autogen, no water reflections and no shadows (don't look relaistic to me anyway). Scenery Complexity is at very dense.I use active Sky 2004.5 with the FPS freindly cloud set from FSskyworld.You should be getting good frames with little hit at AA and AF with that card. What are your other FS setings like?Hope this helps.Glenn

refresh rate you should be fine with 60 hertz on a LCD...They recommend 16x ansio and 4x aa probably for image quality. I find 8x anisotrophic is a great compromise. Looks almost as good as 16x but with less of a performance hit. 4x aniso can also work fine when you are fighting low performance. This is quite individual but for FS I want 30 at least and nothing under 25 ever... some people claim 12 fps is smooth I wish I had those eyes really :)But run in quality mode with all optimizations enabled to start with and first lower 16x aniso to 8x aniso and then 4xaa to 2xaa. If that is not enough try 2xaa and 4x aniso :)Now there is other settings as well. If you have a weak CPU if you can live without AI traffic you can gain tons of performance that way. Same with clouds...

Thank you very much Gents,Just like I though - 4xAA and 8xAF gives the best compromise in terms of quality versus performance.I do not generaly have a performance problem with this setup, only I found that at 1600x1200 my screen started flashing like crazy.I checked the 'lower frequency at higher resolutions' and I also replaced my DVI 12 pin to DVI 24 pin plug - fingers crossed.Cheers again,Dom
