I have a super ASUS 22" monitor with an Nvidia 8800 Ultra. But I find the 75 Hz refresh at 800 x 600 rate is too low for my eyes. When I fly in FS9 to a higher resolution the refesh rates drops to 60 hz. A year or so ago there was a super program that allowed you to increase the refresh artes to 85 Hz which was brilliant.Anyone any idea;s how I can increase the refresh rate to 85 hz?Thank you very muchBest Regards,Chris EGBB

You can't. 60hz refresh rate for 21', 22' or 24' are normal at high resolutions. I mean, that's natural refresh rate for such high resolutions.

I don't mean to be a nudge or anything but doesn't it depend on the refresh rate that the monitor supports? I have a Syncmaster 243T and run it at 85hz while displaying at 1920x1200 because the monitor can support that resolution and refresh rate. One thing to make sure of is that your video card refresh rate is running at the same speed as the desktop. I use an ATI card which has that option.Also check your Windows Event Log, specifically, the Application Log. It might reveal a DLL that has abended and you may be able to find some info that can help at John's website.MarkJohn Hinson's Adventure Unlimited - Flight Simulator Fault Findinghttp://www.adventure-unlimited.org/faultfi...php#Identifying

Yeap, but that exact monitor, don't support more than 60hz on high resolution.

To add to the others...if you have 60 or even 75Hz refresh, but are locked at 30fps, you're seeing 30 frames either way...keep that in mind.

If the monitor is capable of displaying those higher resolutions at a higher refresh rate, there should be no need for any seperate app to get you there. You should be able to go into yr vidcard settings and choose what refresh rate you want to use for any given resolution. You'll have an opportunity to test that res/refresh combination as well. If you just try and force some high refresh rate that the monitor can't support you're likely to get a black screen - the monitor will basically shut off to prevent damage.It almost sounds like you are actually referring to framerate rather than refresh rate though... :(

Gents many thanks for your kind emails, excuse my niavity but can someone explain explain the difference between frame rates and refresh rates in hz. In FS9 I get between 40-70 Frame rates per second but my screen has a refresh rate of 60 hz.Thank you very muchChris EGBB

the "refresh rate" of your monitor is the number of times per second your monitor is physically capable of fully lighting each of its pixels - essentially it represents how often the monitor can physically update the image displayed per second. The "framerate" represents the number of times per second the game you are running (in concer twith yr CPU and GPU of course) is able to generate an updated screen image. The game might be capable of sending 200 images per second to the monitor but the monitor will never display more than its refresh rate can allow.

Many thanks for that detailed answer, so if my FPS is 80 FPS and my refresh rate is 60 Hz, does that mean to say that the highest FPS is actually 60?Best Wishes,Chris

essentially, yes. That doesn't necessarily mean that its not a good thing to be able to run games at higher framerates. Most LCD monitors run at 60hz refresh rate. In FS I like to use vsync to lock the framerate to that 60 hz refresh. I use the VC a lot and I find the screen tearing very notable when panning around the VC so vsync takes care of that. However, you ideally want to be able to maintain framerates higher than 60 fps so that you aren't ever dropping below that becuase with vsync on things can get pretty choppy if the framerate drops lower than the refresh rate. Theres also something to be said for having some headroom. Even if you can only actually see 60fps due to the monitors refresh rate, if yr system is actually capable of maintaining 80 or 90fps much of the time you know you've got room to breathe...

Many thanks hat is very interesting. So is the oppposite true? IE if the FPS drops to 10 or 20 does that mean to say that the refresh rate drops too to 20 hz?Many thanks and Best Regards,Chris

no the refresh rate is a constant. If the framerate is 20 fps and the refresh rate is 60hz, then you basically see the same game frame for three screen redraws...

Many thanks Zevious very interesting.Thank youChris
