Question Computer seems to be running slower than expected

[Dmoore5995]

I have a custom built computer that I use for gaming and also game/graphic design. However, I have found that it runs with relatively poor performance compared to my expectations for the specs it has. Looking to see what I might check to get it where it needs to be. (Will try to post either 3D Mark scores or userbenchmark report if needed)

SPEC SHEET

Looks to be a nice system aside from the low RAM speed. Didn't list a power supply.

What is not meeting expectations?

Oh my apologies. Adding the PSU now.

I built this computer to run the best of the best and not have to worry about things like having a chrome tab open in the background while playing a game and my game engine (UE4) shutting itself down due to lack of resources. Also, I play games such as COD and Forza. On Warzone, I get around 140 frames, but that is on pretty much high settings with a 2560x1440 resolution. However, on some games like Cold War, I get my full 144 frame limit with the same resolution, but it stutters. I have the computer connected straight to a Switch which runs through my Router. I get around 80 mb/s download and 12 mb/s upload. Ping stays at 40. Still stutters.

My main issue is that now UE4 crashes every once in a while with a very small load, just seems random, and so does several other programs.

What type of monitor, refresh rate, sync type?

Is the monitor G Sync compatible, or have you gone into the Nvidia Control Panel and enabled/tried it?

 

[Dmoore5995]

Samsung curved 32" 2560x1440p monitor
Refresh set at 144 Hz
No sync type available.

Have checked on multiple occasions to make sure of this, and there is nothing even indication that it might be compatible with G-Sync or Freesync.

I do run a second monitor, but it is just a 1080p monitor set at 60 Hz. I only use this for text documents, programming, and/or web browsers. (Try to limit my tabs to 1-3)

When trying to pin down a problem like this it makes sense to simplify: after benchmarking, remove all the drives but the boot drive, and only have one monitor connected to the PC. Then repeat benchmarks whether or not you see a difference.

I will do that, but it will have to be when I get home later tonight. Will edit the original question to include the results.

Just as a 'try it and see' it might be worthwhile to game on the 1080 with V sync enabled. Your system is FAR more capable than that, but to see if the stutter goes away.
My thoughts are that the 2K monitor is showing you dropped frames. If nothing else you might be able to set it's refresh lower and enable V sync on it to see if the stutter issue lessens or goes away.

 

[Dmoore5995]

I have played on the system with lower settings before and it did not change much. I will repeat this and try again and post the results tonight as well.
