Blooze Posted October 3, 2015 Posted October 3, 2015 Is there any real benefit to capping frame rates in the graphic lua file and if so what would it be. Could it provide greater stability with performance and/or reduce the potential for problems? Inquiring minds want to know. [sIGPIC][/sIGPIC]
Brisse Posted October 3, 2015 Posted October 3, 2015 Big fluctuations in frame-rate can feel wierd, and capping it will take away the peaks wich means it is more stable, although the average is lower. It is also very beneficial for the power consumption of the PC.
msalama Posted October 3, 2015 Posted October 3, 2015 I'm capping mine at 30FPS (or 1/2 my monitor's refresh rate) because I never seem to dip below, and as a result have no irregular stuttering whatsoever. What I do have, however, is constant motion judder, which is inevitable with framerates this low. Now some people can't stand motion judder and thus never run their systems with this low a cap; whereas others like myself loathe irregular stutters, and thus make do with "lowest common denominator" approaches like this. So it's certainly a bit of a tradeoff TBH. But then, one man's poison is another man's cure isn't it ;) The DCS Mi-8MTV2. The best aviational BBW experience you could ever dream of.

My understanding of Vsync is that you must have hardware capable of producing frame rates of at least 60 FPS consistently before it becomes a benefit and so with my GPU that ain't gonna happen. Thanks for the suggestion. [sIGPIC][/sIGPIC]

Thanks for the suggestion. Correct, otherwise it will cap at 45 or 30 and even fluctuate between these values, unless of course the intention is to cap at a lower value.

Brisse Posted October 3, 2015 Posted October 3, 2015 Couldn't you just enable Vsync which would lock frame rates to your refresh rate??? V-sync isn't the same thing as a framerate limit, although it does cap the fps to the monitors refresh rate, but it also comes with other, potentially unwanted effects such as extreme stuttering when the sim fail to keep the same pace as the monitor. That's because the graphics card has to wait until the monitor is ready to receive another frame. With v-sync you also get more latency, because there is a frame buffer involved which means the frame you see on your monitor is actually 2 or 3 frames old depending on if it's double buffer or triple buffer. A frame-rate limiter is different. It only caps the frame-rate without actually buffering or synchronizing frames with your monitor. It means there will be tearing, but it also means no extra stuttering or latency. The best of all world is adaptive sync. Personally I use AMD Freesync which means my monitor's refresh rate is variable and controlled by my graphics card. The monitor refreshes whenever it receives a new frame. No tearing and no stuttering. You need both a compatible graphics card and monitor though, so not many have access to this method yet.
