FPS maxes out at monitor refresh frequency (60)

Featured Replies

I have been puzzled for a while about this. In FSX I will occasionally get 100+FPS but my FS9 maxes out at 60 FPS. Never goes higher. I am sure it can.Anybody have any idea how this can be changed ?Vista Business 64-bit...Thanks

Vsync is somehow turned on in FS2004 while it is not applied/overridden in FSX.I presume it is an LCD monitor. Do you not have occasional image tearing in FSX with Vsync turned off?Alex

There's really no need to change it, unless you're trying to benchmark...Since your monitor cannot possibly display anything more than 60 FPS (aka: 60 Hz), there's no real benefit to making the CPU work on generating high framerates when it could be busy doing other things, like generating more AI traffic, working more smoothly with textures, putting in higher detail scenery, and other items.Exceeding the frames-per-second your monitor can handle results in wasted processing time... You'd be far better served to continue upping your scenery and detail levels until you've got it as close to 60 as possible, or capping your FPS limiter at 60 to give the processor some time to do other things. From the peanut gallery,-Greg

just in case you do wanna un-cap it, you can set it through nvidia' control panel (assuming you are using Nvidia). Use the custom program feature and select "force vsync off." I have mine on off for benchmark reasons, but yeah, no need to push beyond 60 if you are using LCD screens...-feng

I want a 100 fps in FSX! :(

Using ATI 4750...I think I tried changing vsync but it did not work....will tinker some more...Thanks for the feedback guys.No, I am not really complaining...just curious :-)

I have FSX locked at 30 FPS using the frame limiter tool (while in FSX settings it is set to unlimited) And the same held true for FS9 when I ran using the frame limiter although I could not achieve smooth fluid motion as I am experiencing in FSX unless I shut various services down using FS9 configurator and ran FS9 via FSAutostart which was then replaced by Alactrty IMO I think it is a waste of resources to run either sim at more than 30 FPS, there really isn't any loss of fluidity that your eyes could detect.

there is a HUGE difference between 30fps and 60fps. The human eye can see a lot more frames than 60 actually, but for most people, 60 starts to show images "smoothly." 30fps is way too low for me...i can notice the choppy-ness right away. Anyways, pictures say a thousand words:http://www.boallen.com/fps-compare.html-feng
30vs60 was no different to me... sorry.Which should give everyone a really, really big hint: It's subjective and what's "right" for one person may not be for another.
Agreed... I don't really see the difference between 30 and 60 FPS...

Me too. I do remember Feng once saying "but i do have a bad case of motion sickness if the fps is below 60. My eyes are super sensitive to motion, and any low/skipping fps would give me a headache almost instantly.."Fortunately my eyes are not that sensitive or I would be getting sick every time I fired up the sim since I usually keep it locked at 28 FPS, but everyone is different and I suppose some can tell a difference. Personally in the sim I cant tell much difference once I get over about 28 FPS.
