Re: Best memory management for plenty of VRAM (TESV 32bit)

Thank you for your assistance, Boris. I will try your suggestions.
FWIW, currently the memory section of my preset looks like this:

Code: Select all

ExpandSystemMemoryX64=false
ReduceSystemMemoryUsage=true
DisableDriverMemoryManager=false
DisablePreloadToVRAM=false
EnableUnsafeMemoryHacks=false
ReservedMemorySizeMb=256
VideoMemorySizeMb=11734
EnableCompression=true 
AutodetectVideoMemorySize=true
* since AutoDetect reports the same amount of memory as your VRAMSize tool I thought it's okay to just leave it on and be done with it.

Okay, in the meantime I tried all five of your tweaks. No.1 (and only no.1) actually gives me a slight improvement so thank you very much indeed!

Code: Select all

ExpandSystemMemoryX64=false
ReduceSystemMemoryUsage=true
DisableDriverMemoryManager=true
DisablePreloadToVRAM=false
EnableUnsafeMemoryHacks=false
ReservedMemorySizeMb=64
VideoMemorySizeMb=8000
EnableCompression=false
AutodetectVideoMemorySize=false
I can at least play the game now, like fight off the wolves outside Riverwood. If this was a 10 year old Radeon 3650 I could totally live with this kind of performance. However the stutter I'm experiencing is completely unworthy of a modern, top-of-the-line GPU. :(
Strangely the fps counter never dipped below 44, mostly between 50 and 60 (Vsync).

DisableDriverMemoryManager=true did the trick i think.

Yes, thank you, I agree. It makes perfect sense to disable the memory management of the driver when the driver is buggy.
But "did the trick" is too strong a term. It's playable now in those critical exteriors with lots of forest, yes, but it's still a long way from good. Heck, even zooming and panning in the Skyrim map is jerky with this card!
I should have kept my GTX 980 and saved the money.

It's not about videocard, but drivers. Old are almost always better.

I tried one from March 2017 and it had the same problems, plus some very obvious visual glitches in addition to that.
Should I try even older? Nvidia themselves don't offer drivers for download for this card/OS that are older than March 2017.

No, you can't use old drivers. Rule is simple and never change. If you have old videocard, then must avoid drivers which released together with some new videocard model, they always have bugs. Best drivers are last version before new videocard added to them. All users with new videocards are doomed to wait around 1-2 years till drivers will be okay.

Yes, judging by what I see now I'm afraid you're right.
Anyway, thanks a lot for your help. It's most appreciated.
