SEVERE Driver Issues

Recommended Posts

I've got real problems with my setup...When I run FSX after having used any other games, my frame rates are around 2 - 3 (two to three!!!).The ONLY way to correct this, is by removing and then correctly reinstalling the nVidia drivers.It's just crazy - never seen anything like it!Anyone got any ideas how to stop this apparent damage to my driver files?Doesn't seem to matter which driver version is installed.Specs in sig.Thanks

Do you run FSX with the same resolution as your Windows desktop?Same low fps if you toggle between windowed and full screen mode in FSX?Have you tried to use the UIAutomationCore.dll fix?Have you tried to setup up specific profile for FSX with nvidiainspector or nHancer?Did you install new nVIDIA drivers with the option of a clean install? Did you use driversweeper when installing older nVIDIA drivers?

Hi Ulf, thanks for reply.

Do you run FSX with the same resolution as your Windows desktop?Yes, the same.Same low fps if you toggle between windowed and full screen mode in FSX?Yes, makes no change.Have you tried to use the UIAutomationCore.dll fix?Not heard of this - I'll Google it.Have you tried to setup up specific profile for FSX with nvidiainspector or nHancer?Yes, I use profiles with InspectorDid you install new nVIDIA drivers with the option of a clean install? Did you use driversweeper when installing older nVIDIA drivers?Tried both and always use Drivercleaner.
Hi UlfA very quick Google search shows the UIAutomationCore.dll fix to related to CTD in FSX.My system isn't crashing, its err... crawling :Just Kidding:

You say *any* other games - are youj generalizing or is it a specific game or two? It appears it is the other game problem.If you haven't, follow Nick's guide for setting up NVidia Inspector with an MS Flight Simulator X profile.I'm assuming that a general reboot does not help?Vic

Do you have a game-specific profile for FSX in nVidiainspector or nHancer? If not, it could be that the game you're playing does have a specific profile in the driver, and absent an FSX profile some setting is remaining in an incompatible mode from the last game.If you're not using it already, I highly recommend the free nvidiainspector utility.

I already answered most of that above. I do/use all those above.'All games' referes to all the other games I have installed; MoH Airborne, Crysis, Crysis-2 ans Sniper-Ghost Warior. That's only two different devs, but does mean it can't really be the actual games doing the 'damage'?I've never known anything like this before - bizarre!

You might also try completely powering down the PC, including turning off the power supply (if there's a switch on the back) or removing power from the wall socket. Just shutting down the PC normally leaves power to some components on most ATX motherboards. I had some occasional issues with my old 8800GTX that would cause the video card to go stupid, and that was the only way to kick it back into gear. Cold and warm reboots weren't enough--I had to get all power off the PC for about 20-30 sec to get the video card to reset.

Sadly Bob, it's not that. This has being going on a long time. The PC is powered down every night at the socket.Looking back, this has being happening a long time. Previously, I have done many FSX reinstalls, not realising it was a driver issue.I'm going to try rolling the drivers right back to the orriginal CD version to see what happens...

Did you reinstall Direct x after video driver ??? I would reseat card, clean and check cooling fan etc, and also power to the card is connected and delivering.you can test card ram with this app. http://www.freewarebb.com/Video-Memory-Stress-Test-file4462.htmljust a thought......Ron.
Haven't tried any of that, so thanks Ron.Never occured to me about DX or hardware...

Hey RonJust thought I'd let you know, you may have just 'cracked' that one for me.It's early days yet, but since doing as you suggested, all is still well.It's always good to know you've helped I think.Sometimes it's all to easy to overlook the obvious, so thanks mate!

Hi Phil,In my experience, when it comes to computers, nothing is obvious, I'm certainly guilty of vanishing down the techno-babble rabbit hole and spending crazy days in computer wonderland.only to find the cat had chewed a wire.Hope it stays fine, but keep us informed either way, Ron.

Thanks for your feedback and success, Phil :Applause: In a week or two it's time for my regularly computer clean up. Graphics card out of the case. Case fan filters washed. Compressed on can to blow out all dust from graphics card, mobo and CPU fan. All connectors pulled out and inserted a couple of times to make sure any oxidation is removed. Finally check that CPU temp goes down a couple of degrees. If not - Time to give the CPU fan an overhaul with a brand new thermal paste.This is a standard procedure that I carry out at least 3 times a year.Another standard procedure that I use, which have been criticized here on Avsim, is to use two BIOS profiles. One is a none OC:ed profile that I always use when performing system updates (OS, drivers and such) and other critical activites such as defragmenting with O&O. This is to avoid getting important system files corrupted due to memory failures. A lot of us OC:ers know by experience that even if you've stressed test an OC with OCCT and other tools, your'e still able to get a good system crash when running FSX. A couple of years ago (15-20 years) FS was a recommended application to use when stress testing a system. And IMO still is :biggrin: Just my 2 cents.

To me that is also the best way to go. I look at it this way - it may not be needed BUT if something *doesn't* work, it's one less thing to check. BTW, that's NickN's recommendation also. Can't believe people would give you static about that. Of course, there are those who do not believe in backups either......:)Vic

Sadly guys, I spoke too soon.It seems, that what actually does the damage, is MoD Airborne and Sniper - Ghost Warrior. During play of both, a noticable change is apparant - lag. If I then try to use FSX, my frames are just 2 or 3!!!Is there any software I can use to actually monitor what happens to the drivers?cheers!

Hi Phil,just some questions;1. During play of these games, are you saying the lag starts after a period of time or is happening all the time?2. Are you playing these games On-Line or solo?3. Do you use FSX with any on-line apps. etc.4. What Anti virus program do you use, and do you disable it when playing games?5. Do you have any other Anti spyware type programs.After reading what you have done already, I personally don't think it's a driver issue, seems to me something is maybe running in the background, ie. updates or AV??or if you have been on line, maybe something is continuing when it shouldn't??Maybe we need to look a little deeper.Ron..

Hi Ron1> Starts after a period of time. Never straight away.2> Solo. I never play anything online.3> No online apps with FSX. I don't even use real world/time weather, just user defined.4> NOD32 Anti-virus, but currently uninstalled for checking and monitoring. Makes no difference though.5> No other AV or AS software installed.I've tried running with internet connection dessabled. It still happens. I've also tried using the task manager to close all non essential apps and services etc. I see nothing unusual running either.Seems once it's happend, the ONLY cure is a complete (and correct) driver remomoval and reinstallation.Never seen anything like it!

Hi Phil,well, that eliminates a known culprit with online games, ie. Punkbuster, but check it isn't installed. It is actually a rootkit and flagged by most anti spyware programsDo you have a video card monitoring program like MSI Afterburner, to check temps etc.? could be overheating??Really though, it sounds like you have the culprits, Try completely uninstalling those games and Steam as well, then fresh install. including all patches.I would do one at a time and check for a while before installing next one.This may help BEFORE re-installing drivers;There is the possibility that hardware acceleration or Direct3D is being turned off. worth checking.Press windows logo key (on keyboard with logo flag) + R key at the same time to bring up the 'run' box.Type in dxdiag.exe and press OK. ignore the WHQL message and on the main page check your info for any mismatches.(Note; don't panic if the RAM is only around 4 gig and you have more, it only reports what it can use )Select ..Display tab, check that direct3d, directdraw, etc. are ENABLED and there are no problems reported. XP allowed you to turn these off and on, but not win 7.may as well look through the other tabs, ie sound, to see if there are any reported errors.you cannot turn this ( direct3d ) on directly in win 7, but if disabled, try this workaround;repeat above to get the 'run' box, type "regedit" and open this key (click on the + signs): HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Direct3D\Drivers ( do not click on + sign beside drivers just highlight )Double click (on the right hand side) the text "SoftwareOnly" and change the value from "1" to "0" ('0' is correct ) .Close the regedit program. Now run dxdiag.exe again to see if it worked, you may have to reboot.If this does not work then a driver, directX reinstall is neccessary.hope this helps,Ron.

Just my two cents....When playing those games, do you notice a lot of hard disk action?I had in the past also a problem and it then came down to DISable the S.M.A.R.T. function in the BIOS to save the day.Another possible solution is also linked to hard disk activity. Sometimes it's usefull to disable indexing for the harddisks on which your games are installed.Like I said, only my two cents out of personal experience in the past.I hope you get this sorted as soon as possible.Luc BrusselmansBelgium
