RTX 4XXX Thread

[Neilski]

So this morning i was trying WRC and was stuck at 72fps and 60% load

At first i doubted my power supply or that my system was bottlenecked somehow. A quick google search showed that more RTX4090 users are having the same issue with the game.

In AMS2 VR i do get a full 95%-100% GPU usage.

Hmm, doesn't that simply mean that you are CPU-limited? (I'm not sure which CPU you have, but you can use tools like Process Explorer to check if individual threads of the game's process are pegged.)

 

[HoiHman]

Maybe the 5090 will do it for you

Still have no idea if Nvidia is going to release next at the end of 2024 or beginning of 2025.

Time will tell. For now i happier with Q3 and the 4090 combo then i imagined i would be.

I can even play ACC in VR with a solid 72 fps
The 72hz mode never worked for me on the Index, but on the Q3 it's quite manageable.

Still a lot work to be done, it have ordered an angled adapter so hopefully i can't close my PC case.

Haven you overclocked your 4090? And if so did you use Afterburner ?

No i'm not CPU limited, i think. CPU is also max at 60%

I always have a dashboard running on my center console with CPU / GPU load ect ect.

If you have one thread running flat out on a 12-thread CPU, the CPU will appear to be 8.3% busy but yet you are CPU-bound. Hence my remark about checking the threads in the game process. The bottleneck is always somewhere, unless you have a cap on the frame rate.

 

[RasmusP]

So what's your CPU and what's your RAM speed?
EA WRC easily runs at 60 fps but anything higher and you need a really great single core performance.

Before the first big patch, all stuttering, although even limiting to 75 fps, came from my overclocked 7600X with overclocked ddr5 to 6200 and tighter timings.

Didn't try the new patch yet.

I'm using the ASUS software for my ASUS TUF OC 4090. I only have it set to the first notch, but I've never noticed a difference.

Basically any title that works well has a bit of headroom and isn't maxing out the GPU.

Try to capture your run with CapFrameX and compare GPU and CPU frametime. The largest one is the bottleneck.
If you have grunt left in GPU, try to oversample with DLDSR. Should look much better than native res.

Regarding EA WRC not fully using the GPU, there seems to be a topic about it :

[Old Report] Low GPU Usage and Framerate - WRC - DLSS no change

Stutters on initial track run, texture loading and compiling aside, I am concerned with the low GPU usage and framerate. When running on a 4090 on max settings I get 60-70% GPU usage causing frame rates as low as 50fps on max settings. enabling DLSS just lowers the GPU usage but does not affect...

answers.ea.com

Right now i don't want to dive into it too deep, i rather enjoy the VR games in which the 4090 excels. Will do some bug hunting at later stage when the game has had it next patch.

@Neilski : I am monitoring the CPU usage of core 1, not all others

Still sadly doesn't matter at all if you're not taking snapshots within a few clock cycles. (which is impossible)
The only way to see the real cpu load is by comparing the CPU & GPU frametimes (and an fps limiter/vsync of).
These frametime measurements are the only truth for CPU bottlenecks.

Windows shuffles the load around across all cores, the cores are caching while the others are doing stuff etc.
Some cores are preferred due to lower internal latencies and higher boost speeds, but in the end you can't read anything from cpu monitoring apart from when ALL cores are close to 100%.

 

[RasmusP]

To add to this:
This is Cinebench R15 running with 2 threads. So clearly hitting the CPU bottleneck, since it's a CPU benchmark.

Theoretical max overall CPU load is:
6 cores, 12 threads CPU => 100% / 12 = 8.333% per application thread.
2 application threads = 16.6667% max CPU load.
However the load is 31% with 7% idle load from TaskManager at refresh: High.
31%- 7% = 24% for Cinebench.
So Windows "gained about 7.33% extra load" from shuffling Cinebench around across almost all cores, as you can see in the screenshot:


This is idle:

Yes, and this comes just as I've been about to finally pull the pin on a 4070.
New wrinkle: given that they have said they will discontinue the 4070, will I pay more or less for a 4070 if I wait a few weeks? Will I decide that 4070 Super is actually the way to go instead?

I hear the 50 series is coming in 2025. It will probably drop a chunk when that is released!

LOL. I'm using a 970, and I think I have waited long enough, some might even say I've waited too long already

Right now, my "<=100 W" and "<= £100" rules are long dead, so I'm trying to choose the best value package that isn't stupidly expensive or power-hungry.
The 4070 Ti was never attractive to me (same RAM as the plain 4070, worse overall value in my eyes), but ironically the Ti Super just might be (albeit undervolted), because the extra RAM and memory bandwidth change its value proposition quite a bit... Will see what price it ends up going for in the UK though.

I'm noticing that media outlets disagree about what Nvidia said about retiring cards. Most of them are suggesting that the basic 4070 isn't to be retired but the very first story I read said that it would be. Annoyingly, Nvidia's website doesn't say a darn thing about which cards will be retired so I don't know who to believe; will assume for now that the 4070 will remain on sale...

 

[RasmusP]

Ofc they don't publish anything official. You need to be confused so you buy now, if you don't want to miss the current price or buy the super, if you want the extra performance even if they are a bit more expensive

Or it's just chaos and they have no clue what's going on like Fanatec right now...

 

[Mekonrider]

Just bought myself a 4070 super. Should be a decent upgrade over my 3060ti. I'll give ACC another go but I bet it's still not enough. Hopefully the card will turn up by the weekend.

 

[Neilski]

Are you running 4k, VR, something else really demanding? I had no problems running ACC on my 970 at 1080p.

 

[Mekonrider]

I've got a PICO 4 for VR, I can't play flatscreen anymore. Hopefully by tomorrow evening I should have it installed and AMS2 looking even better than already looks in VR.

 

[Mekonrider]

Massive case of dimishing returns as far as the VR is concerned. I think I'm limited by the headset now. Tried AC with CSP and turned all the options up a few quality levels over what I was already using and turned the bitrate up in virtual desktop and it didn't look that much better. Same with AMS2. It certainly wasn't a night and day difference.

I'm sure it's probably a large quality increase in stuff like Cyberpunk but I feel a bit like I've wasted my money as the 3060ti and the PICO seemed quite a good match now I've got something more powerful to compare it to.

I'll try RF2 and ACC out tomorrow.
