March 23, 201214 yr I just completed a job, hauling chickens, from Hilo to Kahului. I am pleased to say, all chickens arrived with all feathers intact.Shortly after takeoff, there I was faced with around 120km to go, and thought hmm I know what I can do - a little monitoring for the first time. I have not seen too much data on performance here, so thought I would share for those that get into this sort of thing.First, my system specs are in my sig. I wanted to go ahead and do this to have a comparison, as I am about to put a new GTX 560 Ti 2gb card in, to replace my GTX 460 1 gb card .So shortly after takeoff, I first switch to windowed mode - no problem there. Pleased to see vsync actually works in windows mode in Flight , unlike in FSX. One thing, if you have pause on window losing focus disabled, the flight does indeed keep running if you lose focus, however you do lose sound if you do. Would be cool if you did not lose sound as well.I have displayed on my secondary monitor, EVGA Precision graphics monitor, Realtemp cpu core monitor, and a cpu/ram usage meter. Now when I launched this flight, I did not have a clean desktop , ie had couple of tabs open in IE, Thunderbird running but minimized...My graphics options: Shadow Quality set to " High", all other options set to their highest levels. Flight runs at 1920x1080 - my monitor's native resolution. Vsync is set to ON. This flight was done in " fair weather", so had a few scattered clouds.My observations:FPS - very solid in this regard- lowest I ever saw it get was 20fps very briefly, over some very thick terrain, lots of trees, forest crammed full of trees and flying low - this was the exception rather than the norm. Flying into the airport at kaluhui - around 40-45 fps. Rest of the flight, much of which was over water - tapped out at 60 fps which is my monitor's refresh rate - due to Vsync being on... flying over an island in between, around 40-50 fps on average. Overall, what I would consider very solid framerates.GPU Usage - Wow, what a change from FSX. Really uses the gpu. Anywhere from 70% to 99% and in between. GPU temps stayed reasonable, had my fan speed set at 58% in Precision, and on auto - it never kicked auto in for the need for higher fan speed. I think the hottest I saw it get was 75C briefly, usually around 65-70C overall.CPU Core Usage = Like it's predecessor, really gives core1 a nice workout - it stayed pegged pretty high throughout the flight. However, saw a lot of activity off and on with the other cores/threads- have hyper threading enabled - especially in areas where lot of terrain drawing going on. There at one point all remaining threads starting bumping up close to around 50%, however there were times they were very low as well. But they are obviously offloading some stuff to the other cores, and maybe taking advantage of hyperthreading...CPU Core Temps = Not bad all all, undoubtedly due to the way the program makes much more use of the GPU. Whilst apparently they spiked up to around 72C at one brief moment or too according to the max reading in Real Temp - for the bulk of the flight they ran around 50-55c. Not bad at all...System Ram Usage = I have 6gb of ram. Ram usage pretty much stayed fairly constant throughout this flight - around 3.2-3.5 gb.Note on this- this is a great reason to run a 64 bit OS - specifically Windows 7 64 bit , and have at least 4gb, preferable 6gb or more of system ram. A 32 bit OS first, can only map 4gb of ram - and of that 4gb space it maps, some it reserves for system resources - like video card, bios, etc... typically on a 32 bit OS, realistically it can only utilize around 3.2-3.3 gb of that 4gb of ram space. As you can see from my ram usage numbers, that means that good ole virtual memory is going to have to be utilized, and we all know what that means. For good performance, Windows 7 64 bit, preferably 6gb of ram or more...So there are my performance numbers based on the above flight. I do not know, if there is a hit in performance by running windows mode like I did so I could observe, versus full screen mode. I seem to see a little micro stutter in exterior view, especially on fly by when terrain is visible, more so that I would normally see in full screen mode. In full screen, the only time I see that is in a fly by view over heavy terrain, and it is very minor. I am going to make the assumption, that maybe there is a slight performance hit in windowed mode based on this observation.Also during this flight, my cruise altitude was around 6,000 ft.So anyway there is some " approximate" data from my first performance observations. When I do install my GTX 560 Ti, I will certainly do a comparison in the fps numbers.In closing I will say - Most Excellent Job Flight Team! Especially in the performance department, while getting the beautiful scenery to boot. You folks did an incredible job in this area. It is no wonder, we do not have thread after thread with requests on how to get Flight to run well. Don B
