Low FPS with HD textures DLC

[Archer-chan]

Hi,

With the HD texture DLC my FPS reducing sometimes to 20-30FPS when I'm e.g. in a rainy night. I play on Ultra settings.

My specs are:

i5 3450@3.1GHz
MSI GTX 970 Gaming 4G
16GB RAM
SSDs

Do you already have this problem with similar specs? I think that maybe my CPU, especially the low clock frequency, limits the GPU power.

What is your VRAM?

[Hammercannon]

The game requieres a huge amnount of processing and graphical power, and reccomends 6GB of GPU memory. so your 970 probably cant handle the HD textures. though idk if your CPU or GPU would be the bottleneck.

[Pecata]

I doubt that. I am running the game with the HD textures on ultra on gtx770 4GB and I get 48FPS on average at 1080P. It is not the video card...I doubt it's the CPU either. At what resolution are you playing the game? Are your Video Drivers up to date? Are there a lot of background processes eating up resources on your pc while gaming?

I agree with Pecata, it cannot be the video card. I run a weaker card, like Pecata, a 680 4GB in my case and have roughly 45 fps at all times on ultra.

It's not your cpu, the i3 @3.1 is getting 100 fps.

Hi,

thanks for the many constructive answers.

The VRAM is 4GB.
I play with a resolution of 1920x1080px.
There are no significant background processes running.

Edit:
I use the newest stable GeForce driver 344.16.
My OS is Windows 8.1 Pro 64bit.

It is either CPU, insufficient power suply, graphics card in wrong slot (long PCIe 4x) or some driver conflict nonsense. I have the same graphics card (with a little overclock), same amount of memory and a bit better CPU (i7-4820K) and it runs 60-80 FPS at 1080p with everything cranked up to maximum, including ultra textures.

[Archer-chan]

The graphics card is in an PCI-E v3 x16 slot. :)
The device manager doesn't show any conflict.
The power supply has 600W and should supply the devices with a high enough current on the 12V rails.

I will do a CPU benchmark with mordor and show you the results.

Firstly, do you have any FPS problems in other games?

I would suggest going into your BIOS and ensuring that your CPUs integrated graphics is disabled entirely (Intel IGP it should be called)

Secondly, do you lag like that WITHOUT the HD texture pack enabled?

I'm running an i5 4670k, 8gb ram, AMD R9 290 and I'm never dropping below 60fps @ 1080p ultra settings.

Now the problem MAY be the gtx 970s memory bandwidth is a bit low to handle the HD textures -- it doesn't quite have enough VRAM to cache them all, and therefore needs to swap them out yet lacks the memory bandwidth to do so efficiently. My r9 290 has roughly 33% higher memory bandwidth.

Its VRAM is 4GB according to the OP, so is the VRAM of my 680, which has no issues running the game on ultra with the HD textures.

It is not a problem with GTX970. Mine does not have any problem with this game and that little overclock is not so aggressive to make a big difference (2010MHz memory, GPU around 1300MHz on boost).

In other games i have nice FPS.

Bandwith:
I think you can't compare them. The GTX970 uses a better compression algorithm, ergo the computed bandwidth is higher.

Edit:

I logged with the windows performance monitor the CPU load. It was at max 80%. The GPU usage was sometimes 100%. At this points the frame weren't also at 60FPS (I use VSync.).

Unfortunately I couldn't reproduce the rainy night setting with the big frame drops. It was the mission where you must follow Gollum in the cave with the Grauk, the big monster and get the teleportation arrow skill. I play it on german, maybe the monster have other names in the english version.

Edit2:

My fault. The GPU usage doesn't correlate with the FPS. I misinterpreted the log.
Now i did two benchmarks in Mordor's Shadow. One with VSync, one without it. Curiously, the scene with the exploding barrels drops down to 35FPS on VSync, without it i get 55FPS+.

The used VRAM was 3.5GB

Here you see the GPU log during the benchmark without VSync: http://abload.de/img/mordorshadowsvfc8.png

This is a weird anomaly I also noticed. Lotta reviews I read stated FPS drops around explosions, which I did not encounter.

However when I turned on Vsync, i started getting FPS drops.

You should never have Vsync on anyways, unless you're getting really bad screen tearing. It introduces TERRIBLE input lag

[Alchemist79]

Have you checked the Nvidia control panels, "Manage 3d settings" to see if "DSR" is enabled. Also you could try setting "Vsync" to "Adaptive" directly for SoM, and disable vsync and fps cap in the game.
