Ok so i can play like Borderlands 2 or rainbow six siege and on borderlands i can be on around 110fps and then drops down to around 55 or 30 and then only goes up to 70fps. when playing siege get 100fps then 80 then 90 it dosn't matter if i walk around i know my pc easily could handle these games some months ago.

Specs

2x980 msi gaming 4g
I7-4790K non overclocked so around 4.2 ghz
16gb ram
250gb ssd
3tb hdd
msi motherboard don't know hich tho
and i cooler master cpu cooler.
 
try running everything at stock and see how you get on! Maybe the OC isn't stable. Some games are known too, to not play well with OC's. Your system is well capable, so the only thing I can see possibly holding back a little is the 4gb VRAM on the GPU's. Some of the more demanding games will use nearly all of that 4gb VRAM and more depending on what resolution your playing at. At very high res, that's gonna be a limiting factor.

1920x1080 and as i said it worked a month ago and for some reason my browser is getting slower and slower by the day.
 
what kind of GPU/CPU usage are you having? Can you check that whilst at full load, along with your temps. Something could be throttling. Either GPU or CPU. I'd hardly think it's a PSU problem. If the PSU was faulty, then I'd think you'd more likely be having shut downs, and blue screens as opposed to slower frames. But I'm not much of a PSU aficionado, so I'm sure there are others here that could give a better answer on that one.

I never get up to full load at any game most of the time my cpu and gpu won't go over 25% since the games isn't demanding

And i get around 72C* on both cpu and both gpus at higher load i think my pc just isn't thinking borderlands is much of a problem so it just limits my gpu and cpu for the game if only i could put morepower into all games.
 
72 on the cpu is a little high if it's not full load. Id expect temps like that with a prime95 run and a good cooler. With that said it's perfectly safe and for that cpu I think your safe even around the 80c mark or slightly higher, even though naturally you want temps as low as possible. 72 on the GPU is perfectly fine.
it's a bit of a head scratcher. have you tried running just one GPU to see if you get expected frames? Given most titles aren't SLI optimized, perhaps you could try one and see if your having similar in game slowdowns. Maybe test a game that doesn't have SLI support with both cards v 1, and see if maybe one or the other is faulty.

i have tried without sli and it's i think the same i only think the problem is my pc is under estimating the game
 
i don't think it's that. Your specs should be eating that up for breakfast (Borderlands 2, Rainbow Six) You should be pushing ultra/high settings with FPS in the 100-200 mark at 1080p (obviously if your running a 60hz monitor you won't actually be seeing all those frames)

Are the games you play online? or single player? Obviously with online play, your having to display perhaps hundreds of on screen characters, so dips in frames would be expected, specially on large multiplayer maps, with lot of on screen activity.

PCs "underestimating the game" and not putting enough horsepower into it is not a thing. However, if your framerate is unlocked your GPU should be at 100% or close all the time. Try messing with process priorities in task manager and see if that helps. I have a Ryzen 1500X and a 1070Ti and I still sit around 40-50 FPS when there are a crap-ton of enemies around, turning off dynamic shadows would probably help since shadows are very CPU intensive, and from what I've seen also fairly GPU intensive. I've never SLI-ed anything so I haven't learned much about it but Rainbow is supposed to play at least somewhat well with SLI, and you should definitely be getting higher frames, especially on competitive graphics settings.
 


yeah, id agree with that. Some in game settings are crippling for fps. Shadows, post processing, AA +AF filtering, motion blur. All of these eat up resources and frames. Also, although it's SLI setup, it's still limited to 4gb fram buffer, so at 144hz it's gonna fall short. At 1080p unless the game is SLI optimised it will be left wanting.

Even SLI optimized it's my understanding that you are still limited to your highest VRAM GPU. VRAM doesn't work like DRAM, it doesn't just network together like that. To my knowledge, you're essentially just combining both GPU's core clocks, and not at a 1:1 ratio.
