Massive performance issues with new Nvidia drivers

Recommended Posts

Sorry if this is the wrong thread for this but I already asked in the drivers forum and haven't received a response yet. I noticed some serious performance issues with any Nvidia driver that goes beyond 347.52. My fps went from 20-30 (before driver update) to 12-15 and it lags horribly. I noticed this only when using PMDG aircraft and I am running FSX non SE with a triple screen setup in DX10.

 

Further setup information: Win7 64bit, i7 4770k 4,3GHz, GTX770 Phantom 4GB, 500GB SSD, 8GB RAM

 

I am wondering if anyone else is having this issue?

I have found that the GeForce 337.88's WHQL ,give the highest, most consistent FPS over all the following driver versions, at least driving a GTX680 2GB card.  I have stayed with with it. It gives me locked 30's...and is very stable driving FSX:MS, P3D v2.4, XP.40b1, and FS9.

I did a clean install. Uninstalled previous driver via control panel, rebooted and installed only the display driver and PhysX. DId that already a few times but to no avail. It doesn't matter which version unless it is 347.52 and below.

I doubt the problem is with the drivers. Most likely your FSX.cfg thought you got a new display. I would delete all of the Display entries like the following from your FSX.cfg, restart and let them be rebuilt.

 

[DISPLAY.Device.NVIDIA GeForce GTX 780.0.0]

Mode=2560x1600x32

 

You can also move your fsx.cfg to a temporary folder, restart FSX, and let the config rebuild. There may be a tweak or setting that got corrupted.

 

Best regards,

Follow Jim's advice but also consider:

Q1) Has your system had any major Windows updates recently or might you have any new application processes running in the background?

Q2) Are you running any addons for DX10? I believe FSX SE is no more compatible with DX10 than the original FSX.

Q3) Are you using Nvidia Inspector? If so rebuild the Inspector profiles after installing or reinstalling the Nvidia driver and choose Nvidia Inspector settings for DX10.

My performance is also awful. Cut in half. Fps 5-15 on approach. My Titan cannot do 2xSGSS anymore. I used to get 20fps on approach and ground an locked 30 in the air. Now 5-15 on approach and ground, and 15-25 in air.

I also had trouble with several of the later drivers, but the 347.88 worked pretty well for me and now I'm using the 353.12, performance is great on my system and my sim is even smoother then with the 337.88.

Got rid of SGSS, brand new fsx.cfg file... still 20fps in the cockpit on the ground. Nvidia does not care about FSX

So FRUSTRATED. Everything is a chore with FSX. Updated drivers make things worse. Airplanes do not run right. Scenery problems. It's endless

 

Here is my expensive computer sitting on the ground at FT YSSY, NO WEATHER. NORMAL AUTOGEN. NO AI or ground traffic

 

Unbelievable

14 FJRI$#*^$#^&*#$ FPS!!!!!!!!!!!!!!!! I am retiring and throwing my computer in the trash. It is worthless if I have to use old drivers that do not run new games correctly. I cannot afford just a dedicated FSX computer and another computer for other games. Goodbye fs world.

Let me assume,Your CPU must have a serious cooling-problem. Any tweaks recently ?

Let me say that with Xplane I have the very same effect with anything above 337.88 (have not tried 347.52) and I'm forced to stick with those because with anything recent brings immediately stutters and decreased FPS (and xplane uses OpenGL not Directx). Could be a coincidence but I have the same video card: GTX 770 4Gb VRAM. I've read in the Xplane forum another couple of complains on the same tone after upgrading to new drivers and that led me to believe this this card is not  perfectly compatible with new drivers.

Gotta admit the resolution on that pic is stunning. Are you maxing out the sliders ?

Please consider you are running demanding addon aircraft and so must have a strategy of choosing realistic settings to work with your hardware for the optimum experience. E.g. what is the point running FSX above 1920x1080 if your primary goal is using a study addon like NGX? Please don't be one of those users who wants to "max out" all the settings!

Q1) Can you give me your full system hardware spec please?

Q2) Are you over clocking your CPU, if so how high and what temperatures are you getting?

Q3) Check in BIOS your memory is running at it's rated speed either via XMP profile or set it manually.

Q4) Are you using Nvidia Inspector - this is important? If so please tell me what settings you have for FSX.

Q5) Are you running any FSX environmental addons for weather or traffic etc?

Q6) What FSX cfg tweaks are you using?

Q7) Are you clean booting your system for an FSX session? Use the RUN command and msconfig and tell me what processes are running?

Q8) Please try FSX with default or less demanding aircraft and tell us the performance you get?

 

Also please don't give up with flightsim! Yes FSX can be very frustrating but there are other simulators out there:

X-plane

Prepar3d

DCS World free

Flightgear free

FS2004 - still life in that sim (plus you can max out all the settings ;)!)

1080p and no, autogen normal. No AI or ground traffic

 4ghz i7, 16gb ram, win7 x64, ssd primary and fsx on secondary ssd, Nvidia Titan video card

 

Yes but only to 4ghz, barely anything. No trouble in other games or system tests

 

Yes bios setup correctly

 

Yes I follow the guides for NI

 

Asn for weather

 

Only basis teaks like affinity mask 62 and highmemfix

 

same problem trying default aircraft and no weather I only get around 25 fps on ground using no AI traffic and no ground traffic. Or flying above big cities and in complicated airport scenery. normal autogen. NI to 8x AF and multisampling only.

 

something is causing huge fps hits on the ground, my system should be able to handle this and give me 30fps shouldn't it?

Yes, you should be doing better, especially with AI traffic completely off and autogen trees/buildings on Normal.   I have not flown FSX in a while as I have moved to P3D myself but I went through all the pain and suffering you are going through now when I was on FSX and I did have success somewhat.

 

Are you utilizing DX10 via Steve's DirectX 10 Fixer software?

 

Are you liquid cooled on your CPU?   I have a 3930k 6-core I7 running @ 4.6ghz and it's rock solid.   If you can get your processor up a little more your FSX will thank you for it.

 

Do you get the low FPS results regardless of if you are locked or unlocked on your FPS?    

 

Is your FPS low but your smoothness steady and stutter free still?

 

What are your AA settings in Nvidia Inspector?  Completely off on everything?

 

You mentioned default aircraft are also giving you low FPS?    Default FSX should be screaming on your rig at over 60+ FPS.   I remember my default FSX doing almost 200 FPS unlimited in Exterior view during fly by mode up in the sky with a default Boeing 737.

 

There are so many factors that all have to work together it can be a trick juggling it into the right order.

... Only basis teaks like affinity mask 62 and highmemfix

... NI to 8x AF and multisampling only.

 

Q1) What i7 model is it?

Q2) Could you possibly show all the text for the tweaks you're using?

Q3) Are you using bufferpools tweaks?

Q4) Have you tested without the affinity mask tweak? I've never seen conclusive evidence for using affinity masks with FSX.

Q5) You're card should be able to run the highest AF setting, which AF mode are you using? (or did you mean 8X AA?)

Q6) Could you post a screenshot of your NI settings?

And my previous question:

Q7) Are you clean booting your system for an FSX session? Use the RUN command and msconfig and tell me what processes are running?

You don't need one. Just install a second OS for FSX exclusively on another partition or drive.

Install P3D - that should help  :p0502:  I  had enough of fsx - I was looking for a new hobby - but 3PD changed that

I wasn't going to go there but....   yeah.. XD  Pretty much this too.   I quit FSX and stopped flying for 8 months after I got tired of the crashing, poor performance and DO THIS DO THAT threads that contradict themselves and all the guides out there.    One should not require that many tweak guides to get good performance out of anything, especially when the 2004 version destroys it utterly in performance and you are left wondering why you ever moved from 2004 to FSX.    As I still like my pretty graphics and outstanding performance thought, I dropped the cash and jumped into the P3D seat and never looked back.   But...  if that is not an option for you there are still ways to smack FSX upside the head and get it to perform moderately well.

Ok updated the driver again. It seems that only in DX10 mode the fps are bad. I rebuilt my .cfg and applied only a couple of necessary tweaks. Using DX9, the sim runs smooth like a baby butt at a steady 30fps in the PMDG 777 at FTs YSSY. Switching to DX10 and the joy is gone, 5fps now lol... clearly a driver issue. Looks like I have to stay with DX9 now and beg for not getting any OOMs again, oh well..

 

EDIT: Just checked my GPU usage in DX10: 0% :lol:

Yeah, tell me about it! I just don't understand what Microsoft and Aces were thinking with FSX. The fundamental consideration for a flightsim is fidelity. They should have released FS9.2 instead!

 

Switching to DX10 and the joy is gone

 

Glad you've seen improvements. However you must realise that FSX ships with a DX10 "Preview Mode" which is known to be buggy. Many addons are not even DX10 compatible. Most people are running FSX in DX9.
