Hello everyone!

I believe my rig is running way under par for the specs that are in it, any wizards out there got any ideas?

CPU: i9-9900K running at 4.9ghz
CPU cooler: It's an EK Velocity Water Cooling block, I can't remember the exact model, sorry.
Motherboard: ASUS Strix Z390-F Gaming (I'm unsure what the bios version is, sorry)
Ram: 2 x 16gb CorVenRGBPRO DDR4 3200
SSD/HDD: Samsung 500gb 970 EVO M.2 (Windows installed on this drive) x 2
GPU: EVGA RTX 2080 Ti (EK-Vector RTX2080 ti RGB Nickel + Plexi water cooling)
PSU: Corsair RM650x ( 6 years old)
Chassis: NZXT H700 White TG Case
OS: Windows 10 Home
Monitor: MSI Optix AG32CQ

For an example, Elden Ring will constantly dip into the 20-30fps range with bad stuttering, this problem is consistent across most modern games(Marvel Rivals, Lies of P, Cyberpunk etc) I am playing at 2560 x 1440p, but dropping the resolution has no difference on performance. I have insured that I am plugged into my GPU and not my MOBO, Hardware Accelerated GPU scheduling is on (Turning off has no noticeable difference), My drivers are up to date, the in game settings seem not too affect much either.
On my old build ( GPU = gtx 1070ti, CPU = i5 8400, Ram = 16gb) I rarely ever ran into performance issues with Elden Ring.

If anyone has any suggestions that would be greatly appreciated!

Kind regards,

Lewis :)
 
It's power. I know you haven't had any crashes so to speak judging from your posts but it shows. Okay so for one thing I've ran almost the exact same Rig for the last 5 years before switching to 12th Gen and 40 Series. With that said the only difference with you is I had an 850 Watt PSU and I didn't have the same problem until I switch to 1440p. Now I'm not saying get a 750 - 1000 Watt PSU but just a food for thought power is a problem sometimes. What I do recommend is checking your BIOs if it is or isn't up-to-date as sometimes stuttering or lower FPS ingame can usual be a sign of outdated BIOS so............................................................

bios of the motherboard up to date?

is the RAM coreectly set to 3200MHz in BIOS and recognized in windows?

check temperatures while gaming is stuttering/low fps

I have updated the BIOS of the motherboard, made sure both the BIOS and Windows recognize my RAM as 3200MHz.

Temps of CPU are about 60-70c degrees under stress and GPU is about 50-60c under stress.

Unfortunately I haven't seen any improvements to my computers performance

I think you are correct, I have had crashed in the past tbh so it adds up even more with what you are saying, I thought my rig all together was only drawing about 450-500W.

I guess I better start saving for a new PSU lol, thank you very much!!

You COULD turn off turbo through Power Options & see if it makes a difference. It's Control Panel - Power Options - Edit Plan Settings & Change Advanced Power Settings then the pop-up shows; go to Processor Power Management and set both Min & Max Percents to 99 and it turns off Turbo Speeds. Better than going into BIOS and screwing around with it. Worked for me when I had a 2017 Predator Helios 300 when the 7700HQ would throttle at 90' C.

are you using any tuning tools like afterburner?
is there any limit recognized like power, temp. or similar?
how high is the frequency of the cpu and gpu while gaming?

check the performance with 3dmark or similar

undo overclocking and test again
 
Thank you for the response Helpstar! I'll include some screenshots of my 3dmark scores, it seems like the CPU is the problem at least for 3dmark. I am not using any tuning tools btw, I use Intelligent Standby List Cleaner but having it off doesn't seem to have any improvements.

reset the bios,
evetually after that, set the correct boot order and set the ram frequency back to xmp 3200MHz

From what I researched it says I can reset my bios by unplugging it and pressing a metal object against the 2 pins labelled "CLRTC" for 10 seconds and turning the PC back on, does that sound correct to you?
Also when you say correct boot order, the only option I have in my BIOS is my OS Drive.
Also, task manager says my RAM is already running at 3200MHz, do I change DRAM frequency in the bios settings, it has no mention of XMP in my BIOS.

Sorry for all the questions and thank you :)

This would indicate that the problem is not enough CPU performance. Usually when you drop the resolution the framerate goes up. Is your CPU boosting to its max frequency during gameplay?

Here is some screenshots of my CPU usage whilst basically idle, then when playing Lies of P, I have my CPU maximum and minimum power usage to 99% as suggested in this thread so that it's running at base clock speed, Using 3DMark my CPU went up to 90c when it was in overclocked mode
 
I would not worry about your PSU power capacity being the problem.

If you're pulling about 450-500W on a 650W PSU then it is perfectly OK to do that.

The recommendation for doubling your power usage in the capacity of your PSU is a recommendation. Not law. The reason it is recommended is because a PSU will run cooler and quieter, as as a result last longer. Additionally at pulling around half a PSU power output while gaming, means your PSU is operating at peak efficiency.

As long as you comfortably have enough power, then you have no issue with that.

However, more importantly it is worth looking at another point with your PSU. .... You should check how much the PSU can output along its 12v rails. E.g. I have a Corsair PSU, and it can output all it's power spec along its 12v rails. 12v being the rail that the GPU uses. I imagine with yours being a Corsair RM650x that it will do the same. The information you are looking for will be on the PSU box.

For what it's worth ... you should be looking for a PSU that is going to be overspecced by a bit more than half. Otherwise you could be upgrading your PSU again in the future. I have a Corsair RM650i, RM750i, and HX1200i. Mostly due to me not buying overspecced to begin with.

The next thing I would check is your CPU thread usage in Task Manager. You need to right click on that Task Manager tab for CPU, and set it to show individual cores. Then you will be able to see if any one individual core is maxing out. If so, that is a bottleneck. .............. That is unlikely causing you to dip to 23fps though as you played on an i5 8400 with Elden Ring. I would check that first though. Have Task Manager set to individual cores on the CPU monitor, on the Performance tab. Play your game, and find the area where frame rate drops to 25fps. Alt-tab the game and then look at you CPU core/thread usage.

No idea beyond that - your situation is baffling. Are you sure you're running your games on your 2018 Ti, and not the CPU integrated graphics?
