How to fix this? Problem with newest DS upgrade.

The newest update to DS has a huge flaw. If you use the main viewport to adjust anything in the IRay setting, when it comes time to render it no longer renders on GPU but goes directly to CPU. I have a 1080ti and this has happened EVERY time since the last upgrade and many people in the forum mentioned in a previous thread that they have the same problem. The only work around so far is either to save the scene as Texured rather than IRay, close DS, and reopen the scene and then it goes directly to GPU as long as you make no changes. Some have reported that using the AUX viewport to do all IRay settings doesn't make it drop to CPU but that doesn't work for me, it still drops to CPU. I now have to close and reopen DS and reopen the scene before every render which takes forever with that duplicate formula flaw that causes an even further delay... Is there some way to clear the cache or whatever it is so you don't have to close and reopen DS EVERY time to render??? This is such a time sucker and driving me crazy! Is there any way to fix this???

I have a 1080Ti as well, and I use DS 4.12, and I have not had any of these problems. Did you check that your nVidia drivers are up to date?
Yes. They are up to date. I'm actually using the newest Beta. When I mentioned this problem previously, a bunch of people said they had the same problem...
ok, I am using the 4.12 main release. I have not tried the latest beta yet.
use the studio driver instead.
I'm using NVIDIA Studio Driver 441.66 and do not experience any problems.
I was using the game ready drivers before and was experiencing an annoying issue where it was dropping to GPU CPU as well (my issue was slightly different to yours though).
EDIT: I meant CPU not GPU
Do you have a GTX GPU or RTX (20xx)? I understand that 441.66 fixed some problems for RTX cards but not for GTX cards - which is why I haven't installed it as I have a GTX 1070.
RTX2080ti, I was unaware of this.
I recall (with the RTX GPU) older game ready drivers did still work. I think it was every game ready driver after 436.48 that caused an issue.
My downloads folder has 417.71, 425.31 and 436.48 and one of these was the last to work perfectly with my hardware.
If it's different for GTX10xx VC's then this may not work.
I have a 1080 and driver 440.97. Mine occassionally drops to cpu, but only after a lot of tinkering with sizeable scenes.
Good information, thanks.
Ahh - just realised that the drivers I have are actually later than yours ... 441.28
Where do you get the Studio driver? And can I run VR on that?
If you have NVidia GeForce Experience installed you can find it under Drivers.
Actually it's not part of the GeForce Experience app but I was able to find it through Google. Going to install it now.
ETA After I installed the Studio driver, it showed up in the GeForce Experience app but it wasn't there unil I added it through the website. Since I already closed and reopened DS, I can't tell if the issue is fixed yet because closing and reopening DS was previously already letting it use the GPU...
