Where's my FPS Bottleneck? New 1080 TI and questionable FPS performance

38 19 December 9, 2017 at 07:15 AM
Hi Everybody! I'm hoping you can offer me some advice on how I can improve my FPS with some hardware upgrades or software tweaks.

Here's my setup:

I5-2500k OC'd to 4.5 ghz
ASUS Strix 1080 TI
16GB 1600 DDR3 Ram
Dell S2716DGR 27 inch 1440p 144 hertz monitor with G Sync
SDD - 500gb Samsung EVO 840

I just bought the monitor and GPU, and it's a MAJOR upgrade over my old 27" 1080p 60hz monitor and Radeon 6800 GPU. During gameplay on Ultra setting I'm getting between 60 and 100fps in Skyrim (averaging around 70) and in Quantum Break I'm getting a pretty solid 80 FPS during gameplay at Ultra settings.

I enabled G Sync in the NVIDIA utility so I believe that is setup correctly (not sure there is any way I can verify though).

I know the processor is old and I'm open to upgrading it to an i7-8700k, but I wanted to check and see if you, wise slickdeals tech community, thought that would really make things better? Logically it should, but the reason I'm a little skeptical is because I'm running a utility called 'CAM" that monitors GPU load, CPU Load, and FPS, and while the processor is consistently running at 4.5ghz, it's frequently only at 50% or 60% load, whereas the GPU is frequently at 100% load.

Did I expect too much? I thought I'd be getting 140fps consistently on games like these.

Any and all thoughts are greatly appreciated!

Turn down some detail and see if the fps goes up. 140fps at 1440 is a tall order for that system.

Yeah if you're shooting for above 100fps, then don't expect to do it on Ultra in most games. When people say a 1080 ti will do 4k on ultra settings, they typically mean at 60fps.

60-80fps on ultra for Skyrim sounds like you aren't bottlenecked much if at all. I have a 1080 ti on a newer processor and that's what I get for most modern games on ultra running on ultrawide 3440x1440. I haven't really played Skyrim, but Fallout 4 was certainly a beast and their engine typically runs slower than modern games like Battlefront 2 and Destiny 2.

Also make sure that you're running the correct drivers for your motherboard chipset. The generic drivers that Windows loads be default aren't anywhere near as fast as the correct chipset from the board maker or Intel. They can have have a significant impact on performance.

Also, goes without saying but also make sure you are running the latest nvidia drivers, not necessarily the WHQL ones. The most recent drivers released mid november saw an average increase of 30% increase in framerate and as high as 50+%.

Oh and make sure you are using a displayport cable, not HDMI.

IIRC Skyrim only uses 2 CPU cores (significantly, there may be minor stuff on other cores), so if your at 50-60% CPU utilization, check and see if two of the cores are pegged, as that could also be a limitation - but the GPU at 100% is also it, above 1080p and 60fps does take quite a system - you could also try lowering specific settings that are CPU-bound or GPU-bound and seeing if they improve performance or not to figure out which is is limiting performance (or perhaps both are, hard to tell)

Thanks so much everybody. edrock200, I upgraded the drivers and that made an immediate difference. I wouldn't have checked otherwise so thanks.

I'm eyeing a totally new build now and I'm researching DDR4 - there's lots of evidence that DDR4 3200 improves FPS over 2200, for example, but I haven't found anything comparing FPS at 4200 or 4600. So that's what I'm searching now. Check this out if you're interested:

No problem. Glad it helped. I havent seen alot of evidence that RAM speed will help significantly. The last article i saw showed an average of 1-2 fps increase from 2400 to 3200. Some games seem to do do upto 10fps better but they were the exception, not the rule. The article noted that any performance increase sharply dropped off after 2800 and it seemed to be more related to memory timing than to speed. So you can try tightening up your timing if your motherboard allows it or even try a slight overclock.
The overall recommendation was not to spend on ram speed upgrades as any gains would be nominal and not worth the cost.

It also mentioned that if you are running one dimm get a second and run dual channel for better performance.

All that said 1440p at ultra and 4k at any setting is still hard for any rig to achieve. I just built a new rig, delidded 8700k oc'd to 5.2ghz and 1080ti. Hoping to hit 60fps at 4k but we shall see!

I missed that you are running Ddr3, not ddr4. My apologies. Ddr4 will make a big difference, my comments above were about ddr4 2400 vs ddr4 3200.

I'm not sure if ddr3 has the same issue, but ddr4 pricing has gone up quite a bit in recent months, I'm not sure why. So keep an eye out for Slickdeals and jump in fast because they don't last. Last month there was a Newegg deal for $140, no rebates, 16gb ddr4 3000 or 3200, can't remember which at the moment.

I've been keeping an eye on PC parts for ~3 months or so and that was the only day I saw a price for ram with those specs for under $200.

I thought you might be interested in this article, it shows pretty major FPS gains when moving from DDR4 2200 to DDR4 3200 on a 1080ti and 8700k.

I'm doing a new build soon and I'm going to base it on a 1080ti and i7-8700k. Just deciding on the ram spees now, which will them help me pick the MOBO.

You didn't link the article. 😀 I got my 8700k to 5.3ghz @1.35v (delid), and my 2400 ram to 2800, left 1080ti at stock clocks. Full 4k Destiny 2 pushes steady 60 fps (can't test higher as my TV is 60hz) I'm not a big gamer, the kids are, but seems buttery smooth to me. At 1440 ultra/8xaa/max tessellation the lowest fps I see is in the 90s. So even ram got me a few fps I don't think it would make a difference for me personally, but I can understand how true gamers will want this. Thanks for sharing!
