Some games are seriously lagging on Xeon E5-2690v2

[David is Back]

It seems to happen on map segments preloading. Can it bee because of my cheap SATA SSD, PCI-E 3.0 or because AMD GPUs (mine is RX 6660 XT) are screwed up for such games? Should I change my platform, if CS2 which I play most of the time is running fine, and my PC is more than OK in working tasks?

once the card has the data its fine, but when its loading data is where it falls on its face

the cpu not having fast cores isnt helping, but the gpu not having enough bandwidth to load its assets isnt helping either

please watch your own sourced vid or mine and quit spreading fud about bandwidth. The 6600xt has no issues on the 3.0 bus.

Though I will agree on the less than stellar CPU. Not sure I think its to blame for the issues OP, it is just the single part int he system I would be most suspect of with a modern game title.

Outside CS2 which you say is running fine, what games are you actually seeing issue with?

That card only has 8x lanes on PCIE 4.0 right? Yikes, yeah that'll definitely cause stuttering issues in some games when using it on PCIE 3, but you probably won't notice a big drop in actual performance.

Since OP says it happens most when it's loading assets in the background this is most likely the issue.

did you not watch any of them either?
some games are fine, others have major problems holding fps at pci-e 3.0 with that card
it does not have enough lanes and stutters while loading stuff

Gamers flock to the newest unoptimized stuff time and time again (and never learn) so companies have developed schedules to push unfinished stuff out the door and maybe fix it later. That's certainly not helping, but the CPU itself is just old and slow now.

In fact I've been having stutters in 2 games developed by small indie studios. They are both made on Unreal Engine 4, I guess.

pcie 3.0 = 8 gt/sec

pcie 4.0 = 16 gt/sec

But is 16gt/sec enough?

I can't agree, because the OS runs very smooth, and the startup time of most programs is also very low (like PhpStorm, NetBeans IDE, Chrome, Photoshop (which starts up like 3 times faster than on i5 10400F, and that correlates nicely with its synthetic score by the way).

thats per lane
3.0 x8 = 7.877 GB/s
3.0 x16 or 4.0 x8 = 15.754 GB/s

older gpus around its strength need all 16 lanes of pci-e 3.0

if the game is constantly loading stuff or changing scenes when it stutters, then its choked by pci-e 3.0 or its 8 lanes

the cpu has many cores, which helps alot with multitasking, but games do not need many cores and love core performance, which is lacking on the xeons and older cpus

Thanks, so if I change my GPU to Nvidia 3060Ti or 3070 it will become better, or no guarantee?

they are very close performing gpus, but the 3060ti has all 16 lanes available
at pci-e 3.0 it will have twice the bandwidth as the 6600xt


the 6600xt is kinda a useless card
bad combo with pci-e 3.0 mobos/cpus, since its limited on lanes, and on newer cpus it will be the bottleneck

3060ti has best of both worlds, all 16 lanes and pci-e 4.0


but the xeons are not really good choice for gaming
many cores, but very slow core performance
10 cores with ht, but only 3.6ghz

But my old CPU was 3.3GHz in stock with 3.7 in Turbo Boost (2500K). And I did play games before I overclocked it to 4.1 GHz, even some heavy ones (on lower-medium settings, and most of the time I got bottlenecked by my AMD HD7850 GPU). So 3.7-3.8 GHz is not bad at all. 2.3-2.8 GHz, like in newer Xeon generations, is really bad.

Then why don't reviewers tell about this fact? They only tell about "marginal" difference in frame rate between PCI-E 3.0 and 4.0, some of them mention that in case of AMD cards it can reach 18-30%, though. But no one whose reviews I had watched did tell about stuttering on scenes preload.

For some reason my GPU core frequency drops to 0 MHz sometimes (data is taken from the stats in Catalyst Control Center), can it be related to my stuttering, or to the fact that the GPU cores are waiting for new data to arrive into its VRAM?

I have stutters when sprinting fast with Shift key down. The stutters occur in DEVOUR (but they kinda disappeared after I bumped up the minimal frequency of GPU in the game profile, so it cannot drop to 0 MHz anymore) and in Someday You'll Return on map preloads (there is a large seamless world with a lot of details, objects, terrain etc.). Though if I walk and do not sprint, the stutter is less noticable there.

Fortnite is running fine (except the HighRes textures mode, but it is terribly lagging for many people as I have learned, maybe that's because my VRAM is only 8 Gb). CS2 is running fine too, L4D2 is running OK. Though, in Timberborn real-time strategy I have small random stutters when moving around the map with middle mouse key when I have a lot of mobs and buildings in place, so it's certainly CPU related too.

exactly, it cant do anything til the data arrives

its either could be waiting on cpu, but thats more unlikely if its holding high fps elsewhere

For single-core cpu performance, you can run Cinebench. I think this is the latest one. It should be compatible w/Windows 11 also, for those who are running it. You're on Windows 10--right?

Is there another gpu driver to try? Are its temperatures OK during your games?

I'm using the latest driver, because CS2 recommended to update it :) I'll also check the temps with FPS Monitor. Though if it was overheating I would have a constant "slideshow" experience until the GPU would cool down, also the noise from the fans would be very audible, right?
