I know that for some period earlier in the year upgrading to the latest nvidia driver was a no-go unless you wanted your preview window to stop working.
Is that still the case and if not, is there a particular "best version" driver available that you can recommend?
I'm stuck using a mobile 1050 for the near future and looking to see if going from 522.30 to something newer will have a positive effect on editing and rendering times with VP 19
TIA
If you are on mobile and want a driver newer than 522.30 there is a workaround. I would not expect any changes to preview or render times. I did find stability improvements as the older drivers bluescreened my laptop GTX 1050 (another known issue for NVIDIA).
Sadly NVIDIA never got around to fixing this preview bug even though they are aware of it and a previous driver update claimed the issue was fixed.
There's also another possible Nvidia-related issue that involves Intel igpus not working correctly in systems with Nvidia boards unless Windows/System/Display/Graphics has Vegas set to prefer the igpu. Doesn't affect my Xeon which does not have an igpu. Impacts a number of things like 4:2:2 decoding in 32-bit projects and AI FX performance.
fwiw I'm not seeing any problems with my Lenovo listed in my sig using the latest drivers for both GPU's and VP 19
Hi, with latest 536.99 driver, they fixed it, not workaournd need anymore 💪

This is very strange.
Why they would fix only some laptop?
I'm on i9-13900HX and RTX4070 mobile.
You?
You?
Look at my signature

Ah sorry, 😅 didn't advice.
So maybe this fix RTX40xx and not RTX20xx 🤔
We see others people feedback.

That's not true, nothing changed with this driver as far as I am aware. If you are using the laptop in hybrid mode (with iGPU enabled) it will likely have the same problem. Do you have Intel® UHD Graphics enabled?
I submitted a bug report to NVIDIA on this and am doing testing for them. Hopefully they'll have a driver fix before too long.

Yes, I have hybrid mode enabled.
I had it before too, but to have real time FX showing in preview window I had to enable openGL compatibility.
Now I switched it off and it works.
Could this also be related to the hybrid GPU Intel/Nvidia drivers issue?
Yess it is
Just tried the 536.99 update on my laptop and no change. Bugs in Vegas 32-bit mode and FX are still there however the workarounds still work.
Fwiw, I get no hybrid mode icon-indicators and Windows power plan settings have no affect on these bugs... my power plan is set to performance and always-on under battery. Only thing that fixes the FX is GDI-compatible in the Nvidia Control Panel and the only thing that fixes hevc 4:2:2 in 32-bit projects is to set VP in Windows/Display/Graphics to power-saving (Intel Iris igpu).
If anyone feels like opening a support ticket with NVIDIA the question of how VEGAS works in hybrid mode vs dGPU-only is one they'd like to confirm (hypothesis- normal function in dGPU only mode). I'm unable to test it as my laptop bios has no option to disable the iGPU.
Anyway for now I'll stick with the GDI compatible workaround and will report back when there's a fix for VEGAS.

Strange as we have users from 10XX to 40XX reporting this issue and NVIDIA support told me nothing changed in the latest driver. Is VEGAS set to use the NVIDIA GPU in preferences/ video?

I will check in next days when I back home, I will let you know.

@RogerS if your laptop BIOS does not have the option to disable iGPU, you may still be able to disable it in the windows device manger: goto the display adapters and select disable device for Intel UHD Grahics. Next restart the laptop.
I was wondering if laptop users can manually force the installation of normal (= desktop variant) NVIDEA drivers. I am not sure this would work nor be safe to use (I do not have a laptop). The laptop NVIDEA drivers may just be tuned to hold the chip back (lower their performance) as not to overhead and/or to use to much energy. A laptop is focused on energy saving - as it must be able to run on batteries, and I do not see it capable of getting rid of heat as good as desktop can with their fans and cooler setup...
I'll ask NVIDIA if that's helpful for testing to disable it in device manager.
I don't know if is possible to install laptop drivers- at least on newer generation chips there are differences in clockspeed and even number of cores, though this may be dealt with at the bios vs driver level. https://medcpu.com/laptop-gpu-vs-desktop-gpu/ Even if you increased power limits you may not get more power as you hit laptop limits for the wattage it can supply and hit thermal limits.
I'm guessing the hybrid architecture is a main difference of drivers and some screwup there led to the current problem in VEGAS.

I do that all the time with a desktop that has multiple video boards. Only issue I had once was that Win11 wouldn't boot till I moved the hdmi cable after I inadvertently left it on the gpu whose driver I disabled. Might be a problem if that happened on a laptop whose display was hard-wired to the igpu.
NVIDIA doesn't seem to need me to test this. Apparently a fix is in the works, ETA unknown.

This is my setting:
Errata corrige.
Now I no longer see FXs in real-time.
I swear that the FX I had tried (I don't remember which one) I had seen in real-time!
So, I apologise, let's wait for news on the next drivers.
Thanks

Sorry to hear that. Some like pan/crop work in real time even with the driver bug, but you need to do the GDI compatibility workaround like the rest of us.
Aside: VEGAS will work faster if you put dynamic ram preview back to the default value than 0 (0 is to fix render glitches if you get any).

Yes, maybe I had try some pan/crop FX 😅
I will turn on again GDI compatibility.
Just one thing, but if this setting solves it, what contraindications does it cause?
Regarding dynamic RAM, I had read here on the forum that 0 improved performance, I actually noticed that by disabling it I had more fluidity when applying more effects.
