Hi all, just installed a Gigabyte RTX3090 Gaming OC card. It’s an upgrade from an MSI RTX 2060 Ventus.
Fired up MSFS. painfully slow startup, much slower than the 2060, eventually gets to home screen, everything really laggy and ■■■■, unusable. GPU not being used at all according to MSI Afterburner.
System is a MSI Pro carbom MB, i7-7700K, 32GB, M2 SSD, and now the new 3090.
All was ok before the GPU install.
Any clues?
Probably nothing to do with your GPU, the servers are not playing nice.
To be sure though, go into the Nvidia Control Panel and ensure MSFS is using your 3090.
Make sure your system is set to use the new card, there was another post on this last week I believe, let me see if I can dig it up.
Take a look in the nVidia Contorl Pannel, believe it’s in there somewhere make sure MSFS set to use the 3090.
Have you tried uninstalling your Nvidia drivers and rebooting PC then reinstalling the latest drivers ?
Thanks Skypilot, I can’t find that setting anywhere in nVidia control Panel or Geforce experience. The Geforce experience app does see the 3090 though.
Haven’t done exactly that though I did reinstall 511.23 when I put the new GPU in.
When you launch the nVidia Control Panel, and select “Manage 3D Applications”
At the top do you see “Preferred graphics processor”
Failing that, as stated above you may want to re-install driver and select advanced option and perform a clean installation (will remove the original and re-install).
Well I’d always recommend uninstalling the driver before installing your new card and then reinstalling after. If you can’t get it to work maybe try using the DDU tool in safe mode to uninstall and reinstall.
Make sure you read the instructions and take the relevant precautions before doing that though if you aren’t familiar with it.
When you moved to the 3090 your system became CPU limited. That causes stutters and other issues. You want to be GPU limited. So you need a faster CPU or limit the FPS.
What FPS are you getting?
I’ve just set every relevant nVidia control panel menu item to the 3090 and not “default” or “app specific”
No change.
Driver uninstall then install next…
Getting about 3 fps, with the GPU not used at all and the CPU at 5%.
OK, that’s what I’ll try next. Uninstall then re-install.
Then DDU if no joy.
Standby…
This might be a silly question but you do have 2 power connections going to it correct? Ideally on separate rails.
Yes, good point, have you connected the power leads correctly (it uses two rather than the one you had on 2060) and is your psu capable of providing enough for the 3090?
Yes indeed, two separate power connectors from two outputs from the EVGA 850GQ PSU.
Just tried a driver uninstall then clean re-install. No joy. Same issue.
Now DDU
can you check UserCfg.opt .. whats mentioned as “Adapter” ?
Beside of MSFS : let you aleady run a test-tool, like 3dMark and does the result looks like which should be for a 3090 ?
Did you plug in your monitor in the GPU at the back of the PC? Maybe you plugged it in the onboard display output of your motherboard?
What does the in-game fps meter show? Limited by Main Thread or limited by GPU?
Interestingly, Blender can see the card and use it for rendering out, but not use it for viewport rendering which is very laggy…
