Been using the DX10 fixer since release and DX10 forever and am familiar with all the tweaks. I have recently noticed that many of the "go to" tweaks don't seem to do anything anymore. Not sure if it's due to video drivers, the fixer or what.

 

Specifically - BufferPools = 0 , TEXTURE_BANDWIDTH_MULT= 

 

I used to run unlimited FPS and BP = 0 to produce very good results but these settings no longer seem to impact the sim at all. I won't complain as I still get 30-40 FPS in most circumstances on Nvidia surround except at really heavy airports it can drop to 20 or so.

 

I removed the BP= 0 and reset to default 40 on TBM (tried 60 80 120 etc all the way up to 200 which caused a slight FPS loss) and nothing changes at all? I've even tried adding FFT  of .1 which used to give a modest boost but this has no effect either.

 

The only tweaks that seem to work are the AA settings found in the fixer and tuning AA via Nvidia inspector as recommended per the guide

 

Prior to the fixer my GPU used to load up due to SGSS but now it barely goes above 50% , CPU usage is low as well.

 

I've also since removed affinity from the FSX config as it doesn't seem to affect CPU usage at all either. 

 

Wonder if anyone else has noticed this effect or seen similar with the fixer/DX10?

With your system it is going to be hard to see any noticeable changes tweaking.  I'm perplexed as to what you are trying to achieve.  A solid 200 fps, no stuttering and no blurries?  That's boring.  Then you wouldn't have to tweak anymore.  I have a similar system.  Do not use any tweaks whatsoever except that I have my LOD_Radius set to 6.5 and my Texture_Max_Load is set to 2048 (oh, I discovered the other day the DX10 Fixer threw in a couple without my permission in the Graphics section:

 

MultiSamplesPerPixel=4
MultiSampleQuality=8

 

I don't mind it much and perhaps those "tweaks" are what makes my DX10 look so great.  If you have a Bufferpool or any other tweak of any sort, get rid of them.  They are only going to give you problems.  Maybe not in a flight from LAX to SFO or LAX to LAS, but maybe in a flight from SFO to KSEA.  Maybe...  It all depends on where you're flying and what you have loaded.  Throw in some real world weather from REX or AS2012 or OPUS and your FS will suffer no matter what you do to it. The Texture_Bandwidth_Multi is really not a tweak.  It is located in the FSX config by default and the default setting is 40.  The experts advise not exceeding 120 (unless you are running FS9 and then you can go up to 400).  It's different in FSX though.  I now have mine at 40.  I had it at 120 and saw some stuttering so went back to 40.  The higher you set this value the more textures FSX will allocate and copy per frame to the graphics card.   Higher settings can cause stutters where the scenery is dense or "busy".  Lower settings can reduce stutters.  You will have better performance and quality overall by removing all tweaks.  Now, the display driver settings (NI) are important.  I have fantastic fps and perfect AA/AF.  DX10 is absolutely stunning on my system.  If you look around the Internet, you will see that the experts out there, including me, are against over tweaking FSX.  It just causes more harm than good over the long run and creates a lot of frustrations.  With your system, you definitely need no tweaks!

 

Best regards,

The FPS is good, no complaints here. Those had been in my .cfg for so long that after I deleted it and started fresh I noticed no change by adding them back in. At any rate. I just thought it was curious as even with my old 680 2GB they still made a differenece. Now , nothing so I have removed them except HIMEMFIX and the AA stuff. Also bloom seems to do nothing but that seems to be something on the fixer they are working on.

It is a bit of a shock actually but following Jim's advice I removed all my carefully crafted tweaks....

Ran my test stretch over and over again just to see my FPS were identical....

 

Could free me of stutters and unexpected CTD's....

Jim, I don't mean to be rude as you are very knowledgeable person with regard to FSX, but that statement is completely untrue. If you have problems with tweaks then they are either set wrongly or your system has stability issues. I myself run extremely complex add-ons, and since I bought this PC I can't remember the last CTD I had during "normal" operation of FSX. The last CTD was probably back in 2011. In the mean time I have done perhaps a 100 flights (didn't have more time than that) and in the process I have always used PoolSize=0, HIGHMEMFIX=1, FFTF=0.10 and TML=4096. Performance is mostly above 30 FPS and often even in the 50's. Even during my 18 hour flight recently in the PMDG 777 from Equador to Afghanistan my FSX was rock solid and had no freezes or CTDs. Only if I start operating FSX in non-normal way, i.e. constantly loading other planes and scenarios in the same session I might get CTD or freeze, but for the rest no problems at all.

I recommend you use PoolSize=0 under [bUFFERPOOLS], with that system you're gonna get a 30% improvement guaranteed.

So..is it UsePools=0 or PoolSize=0 ?

 

Thanks

I think it doesn't really matter, they both do the same thing. But just in case I'd add PoolSize=0 because I am using that without any problems.

 

[bufferPools]

PoolSize=0

Hi Arjen,

 

Thanks for your kind comments.  I am definitely not going to argue with you (I never argue anyway.... :rolleyes: ).  My comments were probably completely untrue to you and many others.  Tweaks may be good for YOUR system as you have an i5 2500K which is a little below most current definitions of High End (Orbx, me and some others consider an i7 or comparable High End).  Like my system, the OP has what many consider as an Extreme High End and, slowly but surely, our systems will become High End and then go to Low End if we get off the fast moving train.  We really do not need these fancy so-called tweaks that have been out there since 2007 when Acceleration was first released.  That's a long time ago.  Hope you understand.

 

Best regards,

Jim

30% improvement with BP=0 sounds a bit stretched if I'm allowed to say.

Is that what they call high-end nowadays? Well, for FSX I consider my system to be pretty high-end. I think for FSX the consensus for a high-end system is i5 2500K + GTX 580 or better. If I would upgrade now to i7 4770k + GTX 780 then I might barely get a 10% improvement (with perhaps a bit more in clouds).

 

I still don't understand why you think those "fancy tweaks" are unnecessary. Without BP=0 my performance would be 30% lower and without HMF=1 I would be suffering from graphic corruptions (such as skeleton planes).

 

I don't agree with "it might work on YOUR system". As long as your system is a balanced, stable modern day Intel + NVIDIA system then tweaks will work out pretty much the same (and I'm talking from personal experience).

Hi,

 

I tried Jims (no tweaks) theory except for  and it was a disaster,  frames dropped to max 15, continuous  stuttering.   I went back to FSX cfg. tweaks and most things are working perfectly, still to find the holy grail.

I would really like to jump into DX10 but am apprehensive (see specs in my sig - yes it's time to upgrade).  Jim, I uninstalled Alacrtiy PC btw as I couldn't get it to work.  Going good with DX9 with some tweaks in particular that I picked up from a good friend, specifically...

 

TEXTURE_BANDWIDTH_MULT=2800 (yes I know that is unusual)

TextureMaxLoad=9 (not really sure this does anything)

TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=1800 

TERRAIN_MAX_AUTOGEN_BUILDINGS_PER_CELL=800

 

Since I only fly the NGX I have...

 

TEXTURE_MAX_LOAD=4096

 

...and other settings

 

AffinityMask=14 (hyper threading disabled in BIOS)

UsePools=0

UPPER_FRAMERATE_LIMIT=30

FIBER_FRAME_TIME_FRACTION=0.18 (still making small changes but this value seems good for me)

LOD_RADIUS=4.500000 (if I go to 5 it is very noticeable on performance degradation - NGX VC)

MESH_COMPLEXITY=100

MESH_RESOLUTION=23

TEXTURE_RESOLUTION=29

AUTOGEN_DENSITY=2

DETAIL_TEXTURE=1

WATER_EFFECTS=6

SWAP_WAIT_TIMEOUT=2 (I think this is default FSX but otherwise no idea what this does)

 

I don't like to quote FPS, rather am I getting reasonable performance, but typically I get 15-30 fps (smoothish) across the board, weather, AI, airports, etc... and the NGX VC is pretty hard on FPS as we know.

 

I've had a few good flights recently so overall pretty pleased but if I could get similar performance with DX10 then that would really be progress.

You do not need to change any settings to go from DX9 to DX10. Just tick the DX10 box, restart FSX, and go fly. DX10 and soon DX11 for P3D are superior technologies and proven to out perform DX9 and below. You have a decent system (an Intel i7) and I would recommend you look at the fsx.cfg/NI display settings. Placing the following so-called "tweaks" in your fsx.cfg is not smart. You are only degrading performance and your textures will not look any better:

 

TEXTURE_BANDWIDTH_MULT=2800 (yes I know that is unusual)

TextureMaxLoad=9 (not really sure this does anything)

TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=1800

TERRAIN_MAX_AUTOGEN_BUILDINGS_PER_CELL=800

 

Water effects in DX10 should be no higher than 5 and I wouldn't use any higher setting in DX9 too. You need to check out the new AVSIM FSX Configuration Guide and try those settings too.

Jim

So..is it UsePools=0 or PoolSize=0 ?

 

Thanks

 

UsePools=0

 

This is an instruction which tells FSX to leave the graphics buffering size, type and number to the GPU entirely.

 

Bufferpools..

 

All the best,

 Hi Jim,

 

To be honest I'm getting a little confused with all the various advise on the forum and I have also been looking at the FSX guide.  However I've decided to build a new rig over the Christmas break so I can start from scratch.  I'm thinking 4770K with one of the following main boards, probaly the Z87-Deluxe but advice appreciated.  I plan to keep my GPU for now but will add a SSD.

 

Asus Z87-DELUXE Intel Mainboard - LGA 1150

 

Asus MAXIMUS VI HERO Intel Mainboard - LGA 1150

 

Gigabyte GA-Z87X-UD5H Intel Mainboard - LGA 1150

 

Gigabyte GA-Z87X-OC Intel Mainboard - LGA 1150

 

Gigabyte G1-SNIPER-M5 Intel Mainboard - LGA 1150

 

I need to find out if my H80 cooler is compatible with this socket.

 

A couple more questions:

 

When using Nvidia Inspector do I have to re-apply a profile before starting FSX\after a re-boot or do the settings remain once set?

 

For DX10 would you advise I get the recently released shader fixer which I was planning to?

 

I just installed FTX Global btw and it looks pretty good so far.
