GTX 980 Memory issue??

[StrongSad]

Hello

I have an inno3d ichill Air Boss Ultra

Since I have installed GTA V I have had terrible stuttering.

I have tried most things but it seems that when I apply settings over 3 GB memory usage that is when the problems really kicks in. In fact it makes it unplayable when driving.

Since I received the card, Afterburner has never shown more that 3 GB of memory

Spoiler

GPU-Z and all other sys info says 4GB

Spoiler

Is there a stress test for the Vram?

I have some great benchmarks for this card but It does not use the full Vram...

see sig for rest of the set up...

if you want a video of the stuttering I am sure that won't be to difficult to produce.

I have no way I can test the card in another rig as I have no friends who have a PC... LOL billy no mates....

Cheers

There is a known issue with the 970 having 3.5GB of 'fast' VRAM and .5GB of 'slower' VRAM. This has caused stuttering and performance issues with the 970 cards.

The 980, as far as we know and according to Nvidia, does not suffer from the same issue however I'd suspect that any game which pushes close to the 4GB VRAM limit of the 980 will cause a performance drop as the system will have to use system memory instead?

To go from 0.5GB on the 970 to almost 1GB on the 980 seems a little much does it not? If 970 doesn't bottle until atleast 3.5GB, surely even if the 980 suffered the same. It would atleast make it around 3.5GB before causing issues?

Fully aware of Ram-gate on the 970 so it should not be an issue.

The "suggested" memory usage shown in the game is 3.2 to 3.5. That should not be an problem for my card or set up.

It uses a 10 GB page file which I had to increase....

It uses 6 GB of system ram (according to AB)

I get FPS drops at the "optomised settings" down to 15 FPS on the bench marks...

However that stays at 60 when using less than 3 GB of Vram...

I will do a video....

Bare with me please...

OK

early days but...

There was a thread on Reddit that suggested that changing the CPU priorities of the GTA5.exe to High and the GTAVlauncher.exe to below normal had resolved it for some. I am some.
Now running at 3.6MB No frame drops or stuttering....

All maxed out plus, FXAA, MSAA x 2, only frame dips (50 FPS) are in shed loads of grass n tree's n stuff....

I think you will fine the 3072 shown in Afterburner is just a scale and changes when usage increases. Mine shows 3072 but when I tried GTA V I saw it reach 3500.
