1080ti 1080p

[Synawke]

I have a 4790k and a 1080ti driving a 1080p monitor @240hz. I have been having shit performance for the specs of the computer recently. And tried to initiate an RMA for the GPU to try and remove factors for what is causing the problem. EVGA though claims that because it is 1080p the 1080ti will preform worse than a 1070 even at this resolution. Against all i believe in this is wrong. I also see people with the same system as me, at 1080p scoring over 1000 points higher than me on time spy. I want to confirm though. even if a 1080ti is bottle necked by 1080p. It should still preform better than a 1070 at the same resolution? even if only by a little?

It should crush a 1070 at any resolutiin, difference between the teo should be something like this hypothetical:

 

Game x 1080p

1080 ti

180 fps

 

1080

150 fps

 

1070

120 fps

Thats what i thought... this is what they said "Hello,

The numbers you are seeing for the card are about right, linked HERE is another example run.
A GTX 1070 will not perform the same as a GTX 1080 Ti at 1080p, it will perform better. 1080p on a GTX 1080 Ti causes such a significant bottleneck for the card that lesser cards will have a smoother overall performance. We would recommend that you try to run the card with Nvidia DSR mode enabled. That will allow you to run the monitor at a custom resolution above 1080p which will result in a cleaner image and better overall performance.

EVGA"

Define "shit performance" in this case? Dropped frames? Stutter? FPS wall?

just worse FPS that i should be getting. for example in CSGO i hover around 200-300 fps and drop below 200 sometimes at all low 1080p. in Destiny 2 i hover around 90fps and dip below 60fps sometimes on all low 1080p. Just constantly preforming much worse than it should be.

Can you track the GPU usage and the GPU engine usage using Afterburner or gpu-z all throughout the playthrough? It should be at 100%

Yeah. in game the GPU is pretty much at 100%. it is like at 95-100% in game

[System Error Message]

the problem is not the GPU, the problem is your CPU and ram. Make sure you're using windows 10, make sure to run your ram and CPU faster. I used to have similar issues with the titan xp and the i7 3770k but overclocking the CPU, ram and switching to windows 10 solved it.

 

Nvidia GPUs show 100% usage even in a bottlenecked situation. For instance if i run blender and a cpu friendly tile size, the GPU is much slower than the CPU at that setting but still shows 100% GPU usage while if i changed the tile size to a GPU friendly version, it finishes 4x faster on the GPU while also saying 100% GPU usage.

 

Another elitist CS gamer who cant game at 60 fps  . I beat others in ghost in the shell at 60 fps.

Is your motherboard displaying any error messages if it has a debug display?

not sure. it said "AO" right now. it said something different before though. like "04" or something\

Does it happen to be a Gigabyte?

Ok, this might be a long shot. 

 

Shut your system down and go into the BIOS. Then change your PCIe setting from Gen 3 to Gen 2, save the setting and let the system restart. Then test the GPU using a game again.

will do. ill let you know the results after

so it was set to auto. but i set it to gen 2. and the results were the same

The answer is right here OP, you're wasting your time trying anything else.

Does it still show error code 04?

Trust your believe. That EVGA Person clearly doesn't understand how all that works together.

 

It is entirely impossible for a 1080 ti to have LESS performance than a 1070 (or anything lower) "because it is a lower resolution".

The absolute worst case would be: resolution is low, GPU pushes MANY frames, but CPU can't keep up and bottlenecks. Then, a 1080 ti will have NO performance gains over a 1070. However, also no performance loss.

 

The lower the resolution is, the more your CPU have to work. If your CPU bottlenecks a bit, then a 1080 ti won't have the full 50%~ more fps, but maybe only 40%. or 30%. or 15%. Depending on the game, settings, and how strong the CPU is bottlenecking.

 

 

If you, in any game, reduce Settings from High/Ultra down to medium or even low, but fps do NOT change --> your GPU is bottlenecked. In low, AND in ultra.

In both settings, your CPU is most likely the limiting factor.

Example with numbers:

CPU can deliver 90 fps.

GPU can deliver 85 fps in Ultra, and 300 fps in Low.

 

You will never see 300 fps. Why? Because your CPU only can do 90 fps. That's all you will ever get, with any GPU that will ever come out. Unless you get a stronger CPU.

 

 

There are many games, where you will not be able to have 240 fps, even in low settings. Even an overclocked i7 8700k will have trouble doing that (Witcher 3 in Novingrad for example).

 

Look into DigitalFoundry's CPU Reviews on youtube. 

They use Gaming in 1080p @ Ultra, and combine that with a Titan Xp / 1080 ti OC, because the GPU can push so many fps here, that the CPU will still bottleneck --> CPU difference will be shown.

 

Your CPU is bottlenecking in many games. Because 1080p is just so low, and your 1080p is simply that strong in this resolution.

 

 

Also a way to check it: Does your GPU run at 100% usage all the time? Or does it fluctuate? does it sit at only 75% or something?

 

Edit: CPU usage does NOT need to be at 100% in order for it to bottleneck. That's not how games work ;-)

You can even have a 20% CPU usage, and have a hard CPU Bottleneck (for example, when a Game only uses 1 single Thread. others are not used, but the CPU is a Bottleneck here).

Games can not use up every single Core (and Hyperthreaded Thread) perfectly yet.

Ive tried overclocking my CPU and I have my ram running at its highest frequency. It didnt change much. when i had my CPU at 4.8 i saw slight performance gains. but nothing major. and still much lower than other people with the same specs

Yeah that's a bold-faced lie.

 

You might see less performance because your CPU is less powerful than the latest and greatest, but not because your 1080 Ti is somehow less powerful than a 1070.

I don't think anyone has suggested reinstalling the driver yet. Clean it up with Display Driver Uninstaller then reinstall. Try different driver versions too.

 

Just in case make a separate Windows 10 install if you can and see if the problems show up there as well.

Take a look at your CPU usage and GPU usage while playing CSGO, likely you'll be hitting 100% usage on multiple cores, and your GPU will be asleep. 200FPS in CSGO at 1080p at all low is a CPU bottleneck, nothing more, nothing less. You can prove this quite easily by comparing the difference in your FPS between a 16:9 and 5:4 resolution, as it's the only way you can change the CPU load in that game by any meaningful degree (due to the change in FOV).
