Finally got it 3090

[lewisprotips]

Its arrived and installed. However when playing warzone I'm seeing it go from 160 fps to 120 fps and this 40 or so fps drop happens a lot.

Setup
10900k
2x montiors
cosair cooling
750w psu

Anyone any idea whats going on? Also seem to be getting what looks like lag.

 

[lewisprotips]

Really I read it was a 750w

 

[lewisprotips]

What resolution and in game settings are you using? My CPU bottlenecks my 3080 (10700k 5.2GHz)in Warzone at 1440p unless I crank the resolution scale right up and it’s worse on some parts of the map than others. Should be a lot more stable in multiplayer.

Everything high and running 1440p.

 

[lewisprotips]

What psu do you have? Brand? Rating?

Corsair 750W TX750M

 

[lewisprotips]

Check GPU usage with Afterburner while playing, it wont be maxed out because you’re CPU bound. It’ll be lowest in the plane before dropping in and in areas with lots going on like Downtown.

Msi after burner?

No skimping champ when nividia recommend a 750 plus it was OK on my previous gpu. Thanks though.

 

[lewisprotips]

The bare minimum especially with your i9 what's another £100?

Edit: it may not solve your problem but worth considering

Again I didnt buy the 750 to go with a 3000....

Congrats on your card - nice one.

Did you use something like DDU (Display Driver Uninstaller) to clean the drivers before installing new card? I don't think PSU would cause hitching, more likely a crash. Worth doing driver clean, and free.

Yes I did the ddu.

 

[lewisprotips]

What psu would you recommend 1000w?

 

[lewisprotips]

Is this with raytracing on or not?

Yeah pal everything on.

 

[lewisprotips]

What resolution?

1440

Razar mouse mat rgb
Razar mouse
Razar keyboard huntsman
Razar kylo webcam
6tb external hard drive
Elgato
2x 27 inch montiors
Cosair case 3 fans rgb
2 internal cosair fans

Also noticed temps on the gpu were at 72 degrees.

I'm going to run the G-force experience today.

It won't be the PSU, COD is a mess since season 6 started, game is running at great FPS for me but random drops like OP and it feels like a stutter mess even though frames are high.

It ran OK on my 2080 super

 

[lewisprotips]

What do you class as okay though? I've done loads of digging and quite a few complaining about poor performance since season 6, it's pretty much the norm that performance drops when they launch a

No fps drop. It was stable on the super. But season 6 does seem a little laggy. But nothing to warrant a big 40ish fps drop.

 

[lewisprotips]

Its not in some areas its like every 5 seconds or so

 

[lewisprotips]

PSUs are cheap...... also probably good to have an 850 plus for the OC aib 3090s. The real power hungry ones and not like the power constrained zotac 3090

I've got a zotac currently my rog one hasn't arrived yet.

 

[lewisprotips]

Yes but it a takes a little bit of configuration if you’ve never used it before. Or do you have GeForce Experience installed? If you go into settings > ‘enable experimental features’ you can display a performance overlay with alt+r in game which shows GPU usage.

You’ll find that GPU usage in Warzone drops to 70-80% in some areas of the map, meaning that your CPU is now the bottleneck and I think that might be why you’re seeing the drops in framerate.

Done this. I have seen drops to around them figures but the fps remained constant at them times.

 

[lewisprotips]

to test the psu theory is easy peasy, drop the power limit and try again. Try at 80% for giggles.

Do I do this on msi afterburner.

 

[lewisprotips]

What PSU is it? A good quality one might be OK. But if its a bit long in the tooth or not the best unit then its definitely a possibility as others have said.

Corsair 750w 2 months old

 

[lewisprotips]

Just done some more testing. Its many under load that it drops fps if I'm stood still it holds. Once I start moving hard or using say a helicopter it drops 40-50 fps for a second and causes like a stutter/lag.

 

[lewisprotips]

Why would an enthusiast with the best CPU and best GPU want to cut costs on a budget 750w psu?

It would be like driving a Ferari through an economy car wash to cut costs.

Well I drive a mclaren not a ferrari to start buddy. Also if you cared to read the thread you would see I didnt buy the psu for the gpu. I'm simply upgrading my 2080 super. Unsure where I've said this is a new build or that I've bought a 750 for the 3090?
