When I tried out MS Flight, they also fixed the mouse issue. Which means that Dovetail's new simulator will also have fixed it because it's based off of Flight's engine.

For some of us, fps drop is a fact. I have this issue in both FSX and P3D2/3 in the NGX VC, fps drop is about 30%. I've tested it in both windowed and fullscreen mode, same thing. I will disable cursor effects (drop shadow...) and will change the cursors, maybe it's the windows thing?

How do you hide the cursor and un-window FSX?

How do you hide the cursor and un-window FSX?

 

In windowed mode you just move the cursor to the top of the screen over the title bar. In Fullscreen mode you either wait 3 seconds for cursor to disappear or move the cursos over the menu bar.

 

Switch between the modes with Alt+Enter.

After 6 weeks of tweaking a new system with multiple configs I only found out this fact today, although I probably knew it years ago and forgot with my absence.

It seemed no end of stuttering would occur during 'normal' flying, ie DOING things in the VC. When I read these topics I confirmed it was the mouse. Except MASSIVE influence on my performance. I did a test: if I move the mouse in a slow smooth circle around the dash of the Duke B60 (for example) without pausing my frame rate is ZERO fps. Yep sim freezes completely. It looks like a crash except as soon as I let go of the mouse within 3/4 seconds the frame rate is back to rock solid 30fps (with everything maxed out except AI).

At least In know the culprit now. Yes I said ZERO fps not 1 fps. I guess if I repeated circles long enough it may move a frame I just didnt have the patience.

It's almost as if there's a hidden option somewhere: PAUSE_SIM_ON_MOUSEMOVE=1

:(

 

I feel like unplugging the little %$^&*( and buying hardware panels so I never have to see a stutter again.

NONE of the above addons or sliders maxed cripple the performance like the mouse movement does. I need a virtual first officer that can respond to my voice commands to change every setting in VC. That would fix it AND be fun. Does one exist somewhere?

That would work with all planes that use default FSX hardware/software procedure calls etc?

I'm gluing horns on my mouse now to remind me it's the Devils's servant in FSX!

It has to do with hardware rendering and acceleration of the mouse pointer, an interaction between the graphics card driver and mouse driver. Try dumping any vendor supplied driver and using the generic mouse driver from windows.

WOW oh WOW.

I've completely solved it!

(and gained 10fps up to 40 now in flight)

 

First, it only happens in Full Screen mode, which I use all the time. Has no effect in Windowed mode.

So I turned Borderless Gaming ON for FSX window.

Hide menu = full screen.

And now I get ZERO effect (I've been waving the cursor all over the place) and frames up to 50 now out of range of

orbx airport.

I turned off Enhanced pointer precision and also seemed to have now got tooltips working? May be unrelated, may check that.

Tooltips I thought never worked with DX10 on? Havent seen them for years..I can finally set accurate VOR/Headings etc!

 

So Current settings=

Enhanced pointer setting OFF

Borderless Gaming installed.

Run FSX

Window maximized.

Right click BG app turn BG ON for FSX main window

Hide menu.

Im blown away after 6 weeks testing. I think I found my Holy Grail.

Time to install the NGX again and try that.

I've even got LOD =8.5 and no problems.

Hands actually shaking LOL...

Mouse cursor has ZERO effect....

OK now to go and enjoy the sim at last! Oops i missed KJAC but the mountains look so good now I dont want to land

i have a Razor synapse mouse but never install extra drivers - driver just showed HID 2 compliant mouse (from memory) - so problem was occurring with default drivers - thanks Slayer for making me check that but it was default being used.

So there seem to be different reasons for this.

I still get drops in frame rates (though never to 0 fps, rather from 5-10 fps from 30), even in windowed borderless mode with "Enhanced pointer setting OFF", unless placing the mouse cursor over the menu or hiding it.

While reading the latest update from PMDG, I was reminded of many discussions in the past about how a visible mouse cursor impacts performance in FSX.  I'm bringing it up again because in the 9 years that I've been using the program,  I have NEVER experienced any reduction in frames when the cursor is displayed.  Whether the cursor is visible or hidden, my frames stay exactly the same... and I do pay attention to that sort of thing.  Could it be because I've always used a Logitech mouse (and its associated drivers)?  I'm really curious why so many people have reported this problem and I've never once experienced it.

 

M.D.

I've never it experienced either. Two different machines, FSX-MS and FSX-SE. I have however, experienced the "complex aircraft + tons of scenery addons + external weather engine + special effects packages + massively excessive anti-aliasing settings + all the sliders to the right"-fps drop. Anyone else experienced that?

Anyone who claims to have completely "fixed" this issue is flat out wrong. It's a core part of the FSX engine in how the CPU calculates the math in determining what the mouse cursor is "over" in the virtual cockpit. The more advanced the aircraft (more clickable things in the cockpit) the more math FSX is doing.

Agree. On complex add-ons, it's a defintate FPS loss.
