my new i7 9700k is worse!!?

Recommended Posts

My previous setup: i5 6600k, Asus z170, 16gb ram, 1080ti ran pretty smoothly (with fps limited to 25).  P3D settings sensible  not pushing it too hard, all was good.   I recently rebuilt my PC around an MSI z390 board, i7 9700k, 32gb ram, and the same graphics card 1080ti.  All SSDs and P3D v4.4 settings are untouched and precisely the same as before.  But now P3D stutters badly and has 20% lower fps than before with six scenarios loaded to benchmark before and after.  New BIOS settings checked and new memory is recognised correctly at 3200.  I've tried changing fps limit, to no effect.  I'm baffled, after spending £800+ that my P3D performance is worse!  I must be missing something.  Any help or advice is desperately needed please!

Maybe i misunterstood you, but did you port your old install of P3D to the new system?

No software changes, just plugged in all SSDs from the old PC inc dedicated D; P3D SSD to the new board.  all other software and SSDs behaving fine.

Have you installed the motherboard chipset driver?

What OS?

Also double-check whatever virus/security scanning software you are using.  Depending on how it is designed, a large change in your hardware may default the virus scanning software settings back to a "default" setting where your "Exclusions" for any P3D files/folders/drives may have been removed (I'm assuming you do exclude your P3D stuff from realtime virus scanning.  If not, go do that now and see if it helps).

I fully agree with Ryan, this is very important and often overlooked.

All MSI chipset and utilities installed (except Norton).  

Win 10 64bit

No virus scanning. It is  'clean' PC only used for P3D and Oculus, no other software or email.

Thanks for the advice guys, but still baffled why it is so bad.

I want to make sure that I understand correctly. You just added to a completely new build your two old ssds?

If that's the case you will have big issues, windows, motherboard, cpu that was on the other system is not the same as the new one. During installation, windows will optimize the system on base of what you have.

Even you cloned your hard drives there are way too many hardware changes not to create performance issues. With your new system, you should not have any issues on a clean install.

I recently upgraded to a similar system. Aside from my storage drive, reformatted everything and installed from scratch. Runs like a charm. Over the years I have found this is the best way to do it.

Yes, but your Z170 chipset bits are still embedded in the OS and boot sector.  No amount of uninstalling things will change that.  You are faced with a wipe and reinstall.  

I agree with Alex and David

If I understand your process correctly - you just plugged the OLD system drive into the new system - you are lucky that it even booted up.

You will need to wipe and reinstall the OS and everything else. I suggest uninstalling P3D and anything else that may keep registration info.

Take it step by step - there is no quick solution to your issue.

Unfortuntaly that is solid advise,  there goes a few days of your life lol

Before you go the full on reinstall everything method, start small and try to delete your shaders, and delete and rebuild your prepar3d.cfg file and see if that helps.  I went from a 4790k to an 8700k without wiping the OS and I didn't have any major issues.  You have been able to do the "dirty OS" upgrade successfully since Windows 7, you just need to make sure to remove all of the old drivers before you swap the hardware.  Now XP and older was another story 🙂

I agree with vgBaron. I am surprised that your system booted to windows given that you essentially took the system drive from one system and put it in another. You can do that!

Me too. I've been doing my own rebuilds since the mid '90's when I built a 486DX2 (!) - experimented a few times by just plugging everything back in and have never had a successful boot. Wiping clean to me is the only way to go.

Yes you can do that, although generally a better result is to re-install windows to remove the extra baggage.

I've actaully updated my hardware three times (complete new motherboard, CPU, GPU etc.) for this single install of Windows7 that I have.

Can be a little complex though, have to be ready with drivers and then there is the enevitable cleanup via Device Manager (in show disconnected hardware mode) of old hardware related to the old motherboard and drivers etc.

If you know what you're doing it is a perfectly viable way to do it, but a little time consuming and can be prone to requiring a degree of troubleshooting.

Windows even has a sysprep tool for preparing an image based install that will basically install itself on hardware of choice and some backup applications also feature the ablity to automate the process of moving a backup image to new hardware.

i also did that no issiues. 

windows 10 can handle that prety well. 

i was realy surprised when i did it the first time.

only if you have tools from morherboard manufacturer installed like ram drive or other things the have issiues.

but windows does a realy good job.

I ported things over during my last upgrade out of laziness- and I regret it.  Weeks of performance issues, random bugs and all kinds of headaches.  My advice, do a fresh install of everything and eliminate the risks.

I have the same CPU and motherboard as yours with a RTX 2070 and 16Go RAM. I have no stutter and P3D works like a charm. I can fly the FSlabs A320 with almost 30 FPS and complex graphic settings.

I also agree with vgbaron about a full OS and P3D install.

Guys, when he really simply ported everything over to the new hardware, the most probable reason for his issues is once more the shaders. He should delete them and rebuild them.

Besides that, I also upgraded my hardware without a re-installation of Windows 10. But with the correct work done BEFORE switching hardware, that is uninstallation of all drivers related to the hardware that was replaced. Worked like a charm.

If the topic starter did not do this, he has now a full mess on his rig. No wonder performance is bad...

The only sensible advise here!

The likely reason the upgrade succeeded by simply swapping the old system drive into new hardware is because, beginning with the Windows 10 v1607 Anniversary update, Microsoft introduced elements of "OneCore", the realization of its long-standing WindowsEverwhere strategy to merge its server, desktop, gaming and mobile OSs.


A significant feature of OneCore is further modularization and containerization of the kernel with the benefit that more low level device drivers can be relinked by Windows without requiring a reinstallation of the OS. Now a major motherboard/cpu change is more likely to be handled as gracefully as, say, a change of video card.


But personally I'd still be doing a fresh OS install rather than rely upon this new capability.

Did the OP benchmark the performance of their old and new PCs with programs other than Prepar3D... such as Cinebench, 3DMark, Prime95 etc? If these other programs are ok then the problem is limited to Prepar3D and, as others have suggested above, delete the shader cache (and probably all the other P3D autogenerated files using the link titled "delete generated files" in the Prepar3D main folder).

Thank-you guys, very much appreciated. I'm going to do a whole new rebuild and a clean install of everything, Win 10, P3D + scores of add-ons and wiping all four SSDs, no matter how long it takes.  Frustrating, the stupid mistakes I've made, but hey, it's called experience....

And we all love to hear from you again when you are settled with the new system as many of us still dreams :-)

Thanks

MPatrickW,

    One thing you haven't mentioned (I don't think) is what clock rate (Ghz) you are running the 9700K at. Unless you specifically overclock it, it may be running at only 3.6 Ghz instead of something higher - like 5Ghz . I have the same chip and went to siliconlottery.com to pay a few more dollars for a 5.0 Ghz version that they have already tested. You may not be able to go that fast, but you should try. What Ghz did your old CPU run at?
