upgraded to strix 1080 SLI while streaming and barely any performance increases

[gabrielcro]

Hello, I've worked as a streamer for many years. No matter what set up I have tried to get, I have never been able to maximize my set up to stream @ 1080p/60fps whilst still having 144-180fps in game. As a competitive player every frame is important to me, even though for the stream anything above 60 doesn't matter.

My previous set up was a 1080, 32gb ram, i7 6700k. I could stream and play games like Overwatch whilst maintaining 80-120 fps so it was playable. Battlegrounds would run at a constant 60-80 fps with little to no frame drops. However I always noticed intel 4-core processors bottle-necking when playing and streaming at the same time. With the stream off, I'd max out to 144fps for nearly any game at nearly any setting, with the stream on I'd get like 30-60% performance decrease in game. The next best thing was 10-core which are like $2k so I decided to just try the Ryzen 1800x 8-core

My current set up is the 1800x, 2 1080's, 32gb ram. Temps all seem normal, I overclocked the 1800x to 4.0ghz. I messed around with overclocking the 1080s and saw no performance increase but a temperature increase so I reverted. After switching to this new set up, I expected at least a 20-40% increase in performance while streaming. Instead what I got was a 20-40% decrease in performance while streaming and while not streaming. Actually, my frame rate stays the same with the stream on or off which is extremely odd. The current game I'm playing, Battlegrounds, does not seem to support SLI very well. I messed with some profiles and got both my 1080s to do some workload. At first GPU1 was 50% work load and GPU2 was 2-4%, and now they're both 30-40%. I assume something is wrong? Shouldn't they both be 60%+?

As far as drivers go, I assume I got all the right drivers. I tried installing GeForce experience but it just looked like a garbage filler program with no support for Battlegrounds anyways. SLI is enabled, G-Sync is enabled, I've tried fullscreen and windowed modes, no difference in quality really. I've tried playing on the lowest settings and my frame rate ranges between 30-90, with massive framedrops whenever guns are fired/terrain changes. On my previous set up that never happened and framerate was a nice stable 70~

Now I know battlegrounds is not a well-designed game and doesn't properly support SLI, but there is no reason I should get a decrease in performance after clearly upgrading my PC. So I have no idea what the issue could be, I'd appreciate any suggestions~ thanks!

You do know that this might be caused by your PSU as I said in my previous post, right?

I have a spare RM750x on hand, I assumed the PSU unit didn't really matter at all, and I'm not really overclocking any more. Should I swap my current psu for the RM750x? I don't really feel like buying another, even just changing it is a hassle (opening case, unscrewing psu, fishing all the cables I put under the case, unplugging everything back in, putting new psu in, screwing it back in, plugging everything back in, putting all the cables under the case again, closing the case)

It's like a 3 hour shitshow lol

I understand that it's a lot of work but you are compromising the safety of your hardware. You should have never put this PSU in a gaming rig anyway, especially when you had the excellent RM750x

The truth is I didn't have all the cables for the RM750x, I left them in another house. So I just quickly bought this CX750M without thinking about it too much. I was missing one of those type4 pin connectors you plug into the GPU. I have all the other cables. Could I just take 1 of the CX750M's GPU power connectors and just plug it into the RM750x? It's a type4, I think they're exactly the same, nothing could go wrong, right?

The 6700k and 7700k are the fastest gaming cpus, its not surprising. The 1800x does not have better single core performance.

Are you using OBS? Try setting it to use NVENC, so the gpus do the work for the encoding of the video stream.

The stream is not the problem at all, I'm getting bad frame rates without streaming.

I was getting 25 fps on battlegrounds. You can talk about how bad the 1800x is all you want compared to intel, but mechanically it is not possible to get that garbage of a performance, anything below 144fps is unacceptable with this set up..there is something else wrong and I can't find it. Someone mentioned that NVidia and AMD have problems communicating at 1080p, is that true and how should I fix this? I'm thinking about going to 1440p

The 1800X even at 4Ghz, isn't going to have the same kind of single core performance that a 6700k or 7700k is going to have. They, very simply, were not made for lightly threaded applications. They're more of a crossover type CPU. CAN game, but not great at it, and CAN run heavily threaded applications like a workstation CPU, but...still, not great at it. It's very similar to a 6900k, yes.....but the 6900k isn't a gaming processor either....

Then there's the temps you're seeing in the CPU.....invest in an AIO. Would probably help. I'll never understand how people want to try to overclock on air. It's absolutely useless.

I have a H11Oi cooler for the CPU, that's liquid cooling.. I think? I mean there are fans on the radiator but I think the CPU is being cooled by liquid

If the cable fits without forcing anything, you should be OK. The PSU is the most important component in any system. A low quality one could take out other components when it fails, due to inadequate safety features.

Ok I'll switch out the PSU and let you guys know if there's any difference. It really bothers me that just because I lost one of these pin connectors I had to buy a brand new (crappy) PSU.. I basically wasted $80 for a goddamn type4 pin connector to the PSU. I mean I could've probably contacted corsair and got it directly from them, but then I'd have to wait weeks, maybe months, for a stupid cable that just connects to the PSU and it's probably worth like 50 cents. I went to local microcenters and bestbuys and they didn't have the cables separately, only brand new PSUs, and I didn't know anything about PSUs and the employees there probably know less than me

The PSU is fine, highly unlikely to be causing a problem.

Then you should try a remount. No reason for those temps with water cooling.

What are you using to overclock the CPU? AMD's software? Or the bios? Have you adjusted your voltage accordingly?
