[SOLVED] GTX 970 lag issue

[christoffe93]

Hi guys I've been having a lag issue with my build since I built it recently. Everytime I play pubg I get a strange latency delay while making sudden movements the game starts to feel slugish which is very annoying as its effect the speed of my mouse while aiming. It's the same sort of feeling you get from a mouse when the sensor is starting to break. For some reason it's not effecting the FPS what so ever. When I overclock my GPU, CPU and ram the problems not as bad but is still there. I'm running a Ryzen 1200, crucial ballistix LT 2400 and a MSI GTX 970 4gb.

You need to provide FULL PC specs, and more details. What about all other PC games, apart from PUBG ? Do they also LAG/stutter ?

I've not been playing other games pubg is the only one I play. The specs are Ryzen 1200 CPU, GTX 970 gaming 4gb and crucial ballistix LT 2400 8gb ram. I've turned most of the settings down such as textures thinking it would be vram but still not helped. I've not ran into this sort of problem before it's got me baffled, hardware issues usually equate to FPS drops but not in this case. I could be moving the mouse while aiming then it will suddenly slow then I have to keep lifting the mouse off the desk to get the aim to move almost like the sensativitys decreased.

Ok, your current CPU might be creating a problem here, IMO. As far as I'm concerned, PUBG is mostly a CPU-bound game, and relies heavily on the core count/threads.

Your current CPU is kind of weak. Are you playing on 1080p ? Though, I'm not sure about the Mouse LAG.

Yeah I've got it running on 1080p. I've tried upping the GPU settings thinking it would draw stress away from the CPU as I heard somewhere that high settings makes games become more gpu bound but even that didn't help. I also heard that these GTX 970s aren't true 4gb vram apparently they are 3.5gb with 500mb slower vram running 1/7 of the speed of the 3.5gb available vram.

Yes, the GTX 970 has a 3.5GB+0.5 GB Memory allocation/partition. But this isn't much of a concern, unless your VRAM usage crosses 3.5 GB, but despite it passing the limit, you won't notice any significant drop in performance, or stutter.

Accessing the last 0.5GB portion is STILL faster than using the system's PCI-e memory.

Oh right, so do you think it's more than likely the CPU. I have been looking at benchmark result and there don't seem to be any difference between the 1600 and 1200 when it comes to pubg but whatever this is it's not showing up as an FPS issue so maybe the CPU can effect the game still as I don't this 1200 has same amount of L3 cache. Could cache cause issues?

I don't think L3 cache value is going to make a very HUGE difference in performance, imo. The core count, number of threads, and the core clock speed value also matter more in Gaming.

Just a quick update i finally figured out what the problem was. Pubg takes way more than the 6GB of ram that it states on system requirements at first i thought the memory was fine as it was bouncing between 5.8gb and 7.8gb memory usage but it wasnt... While the system was on or going in and out of the 7.8gb usage it was eating into page file memory (virtual memory) which was being off loaded to the SSD. Page file wont allow the system to go past 7.8gb usage apparently its a measure to stop the system crashing so it switches over to virtual memory which is not detectable because virtual memory is slower is effect the snappiness of the game without effecting the fps. I've now learnt my lesson by turning page file off, i would rather the system blue screens so that i know i'm out of memory instead of giving me strange anomaly's. I think this should be covered on a separate thread so that people know what to look out for.
