FSX & SLI

[justpassingthrough]

I see a difference now comparing the 2 screenshots.

Screenshot 1 is True widescreen. Notice the zoom: 1.50 and how far away the plane is.



Screenshot 2 is False widescreen. Same angle. Notice the zoom: 1.50 (the same as shot 1) but this time notice how close the plane is with the same zoom rate. Also notice my FPS.



With wideview false, my screenshots are clipped. With wideview true, my FPS get cut. What to do....

EDIT: 2 more





Zoom rate untouched on these 2

Apparently there is a frame loss on my system but I simply did not notice it because the loss was not 5-8 frames... and I ignore frame counters too.

These were taken at the exact same place (Chicago, runway 32L at about 10am this morning) with the same plane. BOTH are set to exactly 1.0 zoom

Wide Screen Enabled = 16.6FPS



Wide Screen Disabled = 18.0FPS (which is my frame lock)



I am running the new FSGenesis USA Landclass which is based on the latest data so I get buildings in areas you do not if you may be wondering why it looks a bit different. I just noticed I am sitting a few feet forward in the first shot.

So I am loosing about 2-3 frames by setting wide view as it was bouncing up and down a bit.

I do not notice any difference in performance when flying though


Looking at your shots and assuming you were set to exactly 1.0 zoom in both of your shots, it looks like your monitor is stretching the image (just a tad) in wide screen mode. Looking at the bottom of the 2 images (wide and normal) it seems like the runway is a tad blurred as compared to under the aircraft and forward of it.

Also, in normal mode it appears your monitor is not centering the image so the wing tips are both on the screen (that assumes you were at 1.0 in both images) That also assumes you did not SAVE the flight and reboot it because in order to reset the ZOOM correctly you must boot the flight CLEAN in both wide screen and normal mode, setting the aircraft and airport location information manually for each test. If you save the flight and reboot it, the ZOOM will be out of proportion which can stretch or make it appear zoomed in too close or distort the foreground/background ratio making the scenery appear too far way or too close n relation to the aircraft.

So now I would have to suspect one of 2 things about your system: (this assumes you did boot each flight clean with the different aspect switch in the FSX.cfg file)

1. The monitor has incorrect aspect ratio information. Check and be sure you have the latest drivers from the manufacture but it can also be a monitor OSD issue that drivers will not fix. I do not know your monitor however I would check the OSD settings and make sure they are set up correctly.

2. The native aspect ratio of your monitor is odd-ball and has some type of conflict with FSX

Something is not right because if you match your wide screen image to mine you will see my sim displays the scenery down the runway closer where yours looks like its way off in the distance.

You will also notice in both my images the wingtips are in correct relation and proportion to the dome and flat roof airport terminal/hangar location on the screen.

Well that stands to reason. The developers said that raising the value and running the frame lock up would create blurries and other issues. Thats is why I was surprised when you mentioned a few weeks ago a higher FFTF was working better for you.

Well, do you have an idea how I should set it then?

High/no framelock or low/framelock?

Ptaylor and Steve Lacey both said frame lock should be at a reasonable level for the hardware and their opinion is lower is better for rendering a simulation so all aspects of the sim get the hardware time they need.

Lacey said blurred is a sign of resources too low for what the sim is being asked to do. Frame lock and memory (amount and speed) must be balanced for the amount of infomation being rendered based on the sliders and config file tweaks.

Steve is no longer withthe FS Dev team. NickN pointed me to that blog when explaining the settings he gave me for FS9. His setting advice was perfect for FS9 and I have used the same theory with his assistance in FSX. So far, I find nothing that proves his advice or the advice of the FS devs is incorrect.

When I took the screenshots, I saved the flight with the same outside view & zoom, exited, edited the config file for wideview and restarted the sim. I did that twice for wideview=true & false screenshots. I did not reboot my system before restarting the sim on any occasion.

I downloaded the latest drivers for my monitor days ago so I don't think that's the problem. I'm on a 25" widescreen Flat panel LCD with it's native resolution set.

I just don't understand why I'm losing so much performance. With wideview=true, I have to compensate for my loses. I turned down my autogen, scenery, water & traffic settings to achieve the same frames I was getting with wideview=false.

There is the problem I am seeing with the zoom. You do not need to reboot the computer but you must not SAVE the flight when switching from normal to wide screen view or the visuals will be out of proportion, which may be why the wing tips were cut off in normal view. If you boot the flight manually in normal mode (Chicago runway 32L) and set to LOCKED SPOT @ 1.0 zoom your wing tips should be on the screen. If not, something is not right with the aspect ratio either in the drivers, the monitor internal bios or settings.

I am seeing a loss of frames as well but not like yours My monitor is 24" with a native of 1920x1200 so there may be something strange about the 16:9 aspect ratio with 25" TFT compared to my 24" TFT.

I do know my monitor is running the next gen 8bit screen as compared to most which run 6bit

I apologize for my error. My screen size is 22" not 25".

This is the one I have: http://www.viewsonic.com/products/desktopdisplays/lcddisplays/xseries/vx2235wm/ I got it for a much cheaper price at Costco.

I will retake those screenshots without saving while switching to true & false view mode.

I run this one: http://benq.us/products/LCD/?product=63 ... ifications

I just got that one a few weeks ago from advice I received about TFT widescreen


I wonder if dropping the resolution 1 notch may not help. I tried that with mine but I did not like the image quality.

Heres the Chicago widescreen shot.. was bouncing between 15-16, now at 17-18




Just goes to show, it takes playing with the numbers and anytime something is installed that may have an impact on scenery like that lanclass file, it has to be recalibrated.

I'm thinking about getting another 8800GTS for FSX. Right now I have all settings on max except for sparse scenery & autogen, and medium low traffic (with the exception of Light Bloom & Ground Scenery Shadows off). I average 20 - 30 fps over cities and 30++ over terrian (locked @ 32). I was wondering with SLI, would I be able to bump the scenery, autogen & traffic to say like dense and high traffic or would I not see any difference at all? If I'm going to get a 5% increase I would say it's not worth it. I'm looking for anywhere between a 20 - 30% increase = 10 - 15 more fps.

Sorry to come in so late in the thread but I do have someting to add

I run Dual 8800GTX because I run multiple displays  -  1 card runs a TH2Go with 3 projectors attached, the second card runs 2 30" monitors.

I wanted to test the SLi so I attached a single 30" to one of the cards and nothing else.  I ran it in both non-SLi and in SLi modes and gradually cranked up the sliders each time.

SLi mode made no appreciable difference.

Hope this answers your question.

Jim

Check your PM

Checked and back-atch-a


With the right zoom, lighting and angle, its not hard to accomplish

Hilarious PM's! They were great.

I didn't know you were a professional screenshot taker too, lmao!
