I am having fps of 10-14 whenever there is heavy cloud in weather. My GPU is single GTX660Ti running 6026X1080 in 3 monitor nvidia surround.

 

So I would like to check if anyone here use the GTX690 or GTX780(single) for surround 3 monitor setup?

 

Putting the cost aside, will GTX780 better than GTX690 in surround mode?

Sounds like ur having the cursor bug resulting from starting the sim in 2D cockpit.

 

What's your default cockpit start? VC or 2D? With Nvidia surround you can't have the 2D panel open, if you do your sim will be stuck at 10-12 FPS until you quit and restart.

 

Just a guess, sorry if this isn't your issue...

For VC only. Low 10-12 fps only when view span to 3 monitor. Fps go to 25-35 when view is shrink to one monitor. Its definitely a surround mode issue.

You best choose the GTX780 over the GTX690.

 

Only in external view FSX is benefitting form the SLI of the GTX690.

Then this card will give better fps than the GTX780. 

 

In the cockpit , 2d or VC the second GPU is doing nothing and then the power of the GTX780 will give better fps. 

 

Your choice ....

Whoever talks to you about 2D in nvidia surround mode is clearly not familiar with nvidia surround.

 

Nvidia surround does not support a 2D view! This is due to limitations with running ultra wide resolution in triple monitor.

 

Tell me, when u r spanned across the three screens, what's ur mouse cursor looking like? Is it a normal mouse cursor or is it just stuck on the spinning cursor (ie when windows loads u get a spinning cursor). If you are constantly getting a spinning cursor that means some sort of 2D panel is trying to open which isn't supported in the nvidia surround causing it to crash and resulting in locked 10-12 FPS no matter what view you are in.

 

Even if u switch to a 2D panel for a fraction of a second, that it, nvidia surround goes into a "black hole" and you may as well restart your sim as nothing you can do will change it.

 

Make sure your sim starts in VC and under no circumstances hit F10 or change to 2D panel or it's save/quit/restart time.

 

Again - this is assuming that u have a spinning cursor when u observe low FPS

True. seems that 780 is the way to go if it can take care of surround. My only problem is the fps and shutters happening frequently in heavy cloud when in 6026X1080 surround.

My do not have the spinning cursor during low fps. Low fps only happen in heavy cloud in surround. The said heavy cloud hv fps of 35-45 when in 1920X1080. Low fps of 10-15 when in 6026X1080.

Set your resolution back to around 5000-5200 instead of 6000...

Thats more than enough and will give you less lost of fps in clouds.

aha yes, at the moment whenever i encounter bad weather I have to shrink to 2 monitors view size so that I could land with fps at about 18-22. And when the sky is clear I go back to 6026X1080.

 

With the GTX780 I am just hoping for a Max surround view at FPS of above 25 , is that realistic?

Hi,

 

I'm running the following and do not regret purchasing the 690 and I'm sure I'm going to get even more bang for the buck once P3D 2.0 hits the market.

 

System Specs: I7 990X Processor - Prolimatech Meghalem Heatsink with 2 Thermalright Fans - Asus P6X58D Premium Motherboard - 2 EVGA Signature GeForce GTX690 Video Boards - 6 Gig Corsair DDR3 Memory 2000MHz (7-8-7-20) - 2 Intel Solid State Drives (40GB Windows 7 64 bit OS & 160GB P3D) - 2 10,000 RPM SATA Hard Drives - Sound Blaster Audigy 2 ZS - 1 Plextor Blueray Disc (PX310SA) - 1 Plextor DVD/DL Disc (PX-806SA) - Enermax Galaxy EVO 1250 Watt Power Supply - Antec 1200 Case - 3 Samsung SyncMaster T260HD Monitors (5760x1200x32)

 

 

I also run 2D popup panels on my sim, they work fine you just have to make changes to your panel.cfg file to remove the flashing/spinning mouse.

 

So two questions

1. Are you running 2D panels

2. Did you edit your panel.cfg file, if not that may be part of your problem.

I do not run 2D panel at all.

 

What is your FPS in heavy cloud bad weather with the quad Evga 690s?

 

I look at the bench mark at http://www.anandtech.com/bench/product/765?vs=827

It  does seems that gtx690 is well ahead of single 780.

 

In my case, I suspect the bottle neck is the huge number of pixels redraw requirement  that cause the low fps in surround, thus the bottleneck is my 660Ti. Do you think thats a good reason to believe that 1 gtx690 maybe a better choice for my case instead of 1 780?

 

**VC panel is not the cause of the low fps as I have 40 fps in 1920X1080 with the vc panel in view.

I have both a Titan and a 690.

I flashed my gigabyte titan with the gigabyte titan windforce bios the Evga titan hydro copper have the same bios 928/980 boost. You get 12% more Very close to a std 690.

And after some bios modding to 994/1046 boost ( watercooled ) Max boost 1202.

It performs better than the 690.

You can by a evga 780 hydrocopper or go for titan hydrocopper or gigbyte windforce you have 10% more power with the titans and aprox 2-3% less than a 690 .

You have no problems with braked SLI in fsx with 780 or Titan

Will the titan 6gb vram crucial for 3monitor surround at 6026X1080(bezel correction)? Or 3gb vram from the gtx780 is more than enough for 3 monitor surround?

I hv low fps 10-12 whenever there r dense cloud due to bad overcast weather. My current card is 660Ti. My cpu i7-3770K(4.4ghz) is at 72% load in these dense cloud weather, so I figure my bottleneck is the 660Ti in 3monitor surround. But I am not too sure if gtx 780 3gb or titan 6gb will be better for my case. Do you think 3gb vram is enough for my 6026X1080 surround resolution?

When i run with the 670 i have dips the 680 was better but not much,

When a made the change to the Titan is was a huge differens when the 670 get down to

15 -16 the titan still hold 30 fps.

Best Bang for bucks most be the 780 i buyed my Titan in on realease date.

The 3gb vram is more than enough.

Thanks for the information about the 3gb vram with gtx780. I am going to get the 780 next week.
