FPS slowdown on R390?

[Darkenmal]

I'm getting the same FPS (mid 30's) that I get on my laptop, which is a 960m 4gb. Is this happening to anyone else? Thanks.

[MattP]

No... I have a 290 and my fps is 60 mostly with everything cranked, there are FPS jerks a lot though no matter what I set it to.

I'm using that same card, a R9390 and no issues with FPS. My guess is your CPU is the bottleneck and not the GPU in this case. Grim Dawn is heavy on CPU usage. In paricular single core performance helps more than multicore.

I can run Witcher 3 on max settings at around 40fps. It shouldn't be a CPU issue.

Irrelevant I'm afraid.

Grim Dawn very poorly utilizes multiple cores, sadly. Before overclocking my i7-3770k I was having frequent FPS dips to 40, sometimes 35 range (I had tried practically every other solution out there, clearly wasn't related to anything but the CPU). After overclocking it, that is gone.

Extensive testing of CPU usages shows that Grim Dawn really only utilizes the first core (which before I overclocked my CPU would essentially always be at a 100%) and every other core is at best at 10% if used at all (which, for instance, is not the case with The Witcher 3 which I too could run at max graphics and steady 60 FPS at all times with my GTX 980 and stock speed CPU). Nothing you can do about it really.

To be fair you can't compare performance between two vastly differance games regardless if the gfx are better. The two games have differance engines, optimized differantly, etc.

It would help if you posted your full specs and not just the GPU. (CPU, RAM, etc)
The 390 can run this game very well, so I doubt that is holding your FPS back.

Makes sense. It is based on an older engine after all. How much did you overclock your CPU?

Sure thing. Here are my specs.

Overclocked from 3.5 Ghz base to 4.4 Ghz. Before heavy combat in Grim Dawn would drop me from 60 (well, technically higher without V-sync) to 30-40. Currently heavy combat keeps at a steady 60, on rare occasion to 50-55.

Im using a amd fx-6350 cpu ( no OC) and a hd 7970 and the fps is all over the place.

Your particular CPU isn't that bad, and is decent at multi threaded operations but unfortunately it's weakest point is single core performance which is what Grim Dawn relies on. Unlike most newer games. IE the Witcher 3 uses REDengine3 which is able to use all your avaliable cpu cores.

For referance I use to get around 40FPS in Grim Dawn using a i7 920 @ 3.6ghz. I've since change my CPU to a 6700k@ 4.8ghz but using the same GPU the 390. Now I get for the most part well over 100fps, with dips in FPS every so often.

Was just gonna buy this game, but I think I'll pass after reading this thread. I have an FX8350 and 2 HD7850's in crossfire. Would installing to an SSD help the FPS issue?

Thanks for the explanation!

A SSD should help loading times and any stutters caused my HDD access for textures etc, but in game FPS wouldn't help a whole lot. Overclocking your CPU would give the biggest FPS jump.

This game is great and would be sad you see you miss it over worring about the performance.

Yeah I really like it myself despite the low FPS. It's a really good ARPG.

@Darkenmal, I would try adjust some gfx settings and see how it goes. A number of the settings are likely to be reliant of the CPU and lowering them could increase performance.

IE just try set everything to low and see what your FPS is like. If your FPS jumps up alot turn one setting up at a time and see if it effects your FPS much until you can get a good balance.
