Simviation Forums

Hi!


I posted in here a while ago, asking help for solving annoying issues such as choppy/laggy panning and turning, graphical spikes when panning and turning etc. I remember Nick tried to help me, but I still have been unable to sort it out.

I have read many, many, MANY tweaking threads and guides, but all my attempts to fix this have failed. Naturally my problems would sound like a bufferpools issue, but no. I have tried every value from 5000000 to 400000000 in 5m increments. It doesn't appear to have ANY difference at all. I have also tried one or two other tweaks, such as AffinityMask and adjusting texture bandwidth multiplier. i have tried changing every setting in the simulator. My system is certainly up to this game. For example:
I take off at KSEA with the Learjet in virtual cockpit view. Everything runs butter smooth, constant 60fps (vsync on). As soon as I lift up and start turning the aircaft, everything become very choppy and i start seeing craphical "spikes" or artifacts. If I go to the spot mode and pan around the AC, it's plain horrible.

What's up with this guys? It's completely ruined my flightsim hobby and i don't even have FS9 anymore

We need to know also your various graphic settings in the game. Some of them have to be avoided, like maximum water setting for example.

Here is my point of view:
- set your bufferpools to 40.000.000 and leave it there for now.
- leave your TBM to 70 for now, it's

Lock your FPS to 30. i7 cant run unlimited with good performance.

Hi Revolution,

I'm certainly not the expert Nick is, BUT his suggestions have my flights smooth so I'll share my setings.

i7 920 step C0@3.8/3Gb Mushkin 7-8-7-20 ( BCLK 190x20)@ 1523 speed/Nvidia 260 with182.50 drivers and nHancer using 8xSQ/no bufferpools/no tree lines. Heavy weather does impact smooth flight wht 8xSQ but I like no tree shimmer. FSX on 80Gb Raptor(I had in an old PC), 150Gb Raptor for OP( XP64).

Now, here is the hit: I have a number of different FSX cfg files for different AC. For instance, I can use unlimited frames with the CS 767 or LvD 767. My 'normal' setting for default AC and Alphasim 105/104 is 75% complexity/75% autogen/ UT2@ 25% commerical(no GA)/water low 2x.

I have GEX and UTUSA/Europe set up as Nick suggested. The only REX I use is water and water animation. My clouds are FEX and I will use ASA or REX or FSX real weather at times.

Some cfgs for some AC use low 1x water.

I have also tested my BLCK@160 which gives me RAM speeds of 1604 (rated@1600) and did not see much difference in the smooth flt.

I also will quite often let FSX rebuild a new cfg file plus I defrag after any AC add-on.

My 260 is OC with EVGA precesion but running a bt hot ao I'll set back to normal (don') see much difff anyway.

I guess I'm suggesting try BCLK@190 and also use the Baron or Cessna.

My test flights are in different areas: Richmond,VA/JFK/IAD/DCA/KFCI/London and weather is fair or building storms.

I did a CS 767 ILS to KATL in CAT 3 conditions (RVR 1400') yesterday using unlimited with no problem. Depending on the cfg setting, I will get the occassional jerky turn so I repeat the turn with lower auto and it is smooth.

Hope this helpls; I do suggest trying lower i7 speeds as a test and use the same test flt always so the test conditions are stable.

Thanks for your answers!

very interesting. I will try what you suggested.

Thanks!

Thanks for your answers!



Okay, I did everything you suggested, and things got better, so we're going the right way here. Still some strange choppines and occassional 'gfx spikes' I set FPS limit to 30 and it seems to do well.

My settings are as follows:

Graphics

-target fps: 30
-filtering: trilinear (AA checked)
-global texture res: very high
-dx10 preview: off
-lens flare: off
-light bloom: off
-advanced anims: on

All good excepted the AA. Unselect it, this in-game AA has a terrible performance. Force the AA from the video drivers instead.

Aircraft

-set to default ultra high

Good.

Scenery

-level of detail radius: large
-mesh complexity: 80
-mesh res: 10m
-texture res: 7cm
-water effects: low 2.x
-land detail textures: on
-scenery complexity: extremely dense
-autogen density: very dense
-ground scenery shadows: off
-special effects detail: high

Put your ground textures to 1m instead of 7cm. Only the taxiway/road textures will be affected, and they will look good nevertheless.

Weather

-set to default ultra high

Reduce the cloud draw distance, clouds are a FPS hog, especially with the default textures.

Traffic

-airline traffic density: 30
-general aviation: 0
-airport vehicle: none
-road vehicles: 0
-ships/ferries/leisure boats: 10

All good

EDIT: About the temperatures. I'm luckily a hardware enthusiast and do alot of benching and testing, so my components should be all fine.

Perfect, that's one cause eliminated then, so we can focus on the sim settings.
Those spikes and graphical glitches happen when the sim does not send the data to draw fast enough (or too fast) to the video card.
The TBM is usually the main cause, but the bufferpools is also important. Of course, the values of those two are closely linked to the rest of the tweaks and game settings. That's why you have to choose the values very carefully. It requires patience and provides a great amount of frustrations, unfortunately :/

"If I go to the spot mode and pan around the AC, it's plain horrible."

In my opinion, never use spot view, use locked spot.  No matter what your settings nor the power of your pc, it seems spot view causes stuttering for everyone, in my opinion.  I have disabled spot view to avoid it.

I assume you know you have other views.

I'm sorry if this repeats other information in previous posts.

Try 20 fps.

I re-installed FSX on a new high performance system. I was struck by the automatic fps limit of 20 fps.

-scenery complexity: extremely dense
-autogen density: very dense

Scenery complexity is a resource hog , you might want to turn it down a notch or 2, autogen is good.

Use Nvidia drivers 182.50! Before those I used the newest drivers... stutters all the way. With 182.50... smooth. Of course, I also use bufferpools, affinitymask and TBM. Nothing else.

Revo:

Let me tell you the unpleasant truth:

YOU WILL NEVER BE ABLE TO RUN THIS FLIGHTSIM GAME  WITHOUT STUTTERS AND CRASHES AND BLUE SCREENS NO MATTER WHAT TWEAK, HARDWARE OR SOFTWARE YOU INTEND TO USE!

That is a fact, an unpleasant fact, and people won't admit it!

Yes, now that we have been expertly warned, back to the regularly scheduled program, already in progress.....







=====================================


I've got
i7 920@4.2ghz


==========================================


I have to question the stability and the temps of that clock. It is VERY rare to see a i7920 hit 4.2GHz without problems which is one of the reasons why they are much cheaper than the 950/975

Just becuse you dont see crashes and the load temps are showing just within range does not mean you are not overruning that CPU with heat and forcing other problems.. and that includes liquid cooling too.

The symptoms are very similar to a overrun CPU, or, PICe system and of course drivers can also dictate success which is one of the reasons I run the 182.50 driver that has been shown to be the best driver for FSX time and time again...

yep, 182.50

will edit the typo
