Interactive rendering slows down.

[fatherrain]

No, I couldn't solve the problem. I use the default Ram settings via Bios. If Expo is open, there is a slowdown. Motherboard, processor, Ram are all new generation. I think these errors will be fixed in time. I will write my experiences after a few updates.

its happen only on ryzen and corona for a month lf solution (some ppl say on win 23h2 no bug)
p.s 9950x + expo same bug

[fatherrain]

I got used to using it without opening Expo. I'll try and update my BIOS, including the BIOS. I'll write the latest status here.

Please make sure to try with latest Corona 12 Update 1 Hotfix 1 too, there were related things addressed in it.

I'll try to go back to win11 23H2, as i did not change anything in bios / ram / expo since the update.

Also 9950X, maybe 24H2 is faulty with this CPU...

I'll let you know if i succed to go back in version, and if the bug is gone.

I don't think it's related to the Windows version. Update the bios. Keep your RAM settings as default. Don't open Expo. Try it this way and let me know the result. You also said that you have the same problem. Can you write your exact problem? Is there a lag in the scene during interactive rendering or is IR opening late?

[fatherrain]

I updated my system. bios, drivers, corona, windows etc. are all up to date. Unfortunately my problem is not solved. If Expo is on, IR slows down the system. I installed 24H2 when I got my system and have never tried 23H2. I need to format the system to test with the old version. I would be happy if someone could confirm that the problem is related to the Windows version. If anyone has this problem and runs IR without any problems with Expo open on an x870 system, I'm very curious how they did it.

Hey guys, could you please try with Corona 12 Update 1 Hotfix 1 which was released 2 days ago and let us know here if there is any improvement?

So, i've updated the BIOS (Asus Tuf Gaming X670) to the second last version (last one is still beta).
And it looks like the lags are gone... At least after 5-6 mn playing with IR

I'll post here if it comes back.

PS : i've also installed Corona 13 daily build jan 10 2025, as suggested earlier
Oh, and i let rams in EXPO (6000 instead of default 4800). Windows find them @6000

Still in win11 24H2, as my rollback was expired (menu grayed out)

[fatherrain]

I didn't notice the last update. I can definitely say that there was an improvement when I updated. I don't experience any slowdown issues when Expo is open. I hope there will be no more problems. Thank you maru. So, what is the correction made and what caused the problem? Do you have any information?

[maru]

Basically, there were some improvements made to the VFB code.

I was happy too soon. Disappointment again. Corona hotfix 1 did not make any changes. I tried it on a simple scene. I thought it worked. Now I returned to work and started working. The result is disappointment. I closed the Expo. Everything returned to normal. If people other than me are experiencing this problem, I think it is not a hardware problem. Which I was afraid of at first.

I think it is related to 24H2 and I am thinking of formatting my system with 23H2. Total waste of time.

If anyone can open Expo with 23H2 and has no problems, I would be very grateful if they could at least tell me about it.

I don't know if the Corona team will hear our voice and produce a solution. I really don't know if the problem is related to Corona or not. I don't know if anyone would say that the problem is not about us. My only consolation is that at least I can do my work while Expo is closed.

Maybe you can just not use EXPO until bios / chipset driver / corona / windows 11 new release ?

Same issue here, same CPU... I did upgraded bios (not the beta, but the second last one), upgraded chipset driver, installed corona 13 daily build from jan 10 2025... and it acts very better, no more long lags / stuck PC... after one day, i just had to reboot once because of afterFX and windows explorer crashed

Oh, and i let EXPO on in bios.

[fatherrain]

I installed Bios as beta. And I made all the updates you mentioned. It worked fine for a few seconds while working on the file. Then it completely collapsed. As you said, I will wait for the new version. So are you using 23h2?
