GTX 770 performance

[Ted Snark]

This is a very weird problem for me. My GTX 770 makes games judder even though tests show that it gets very decent FPS. I did Unigine Heaven 4.0 test just now and got over 1800 points from it. Still even in Unigine tests the picture juddered even though the FPS was very good. Even in the first Borderlands game there is slowdown in larger areas whereas my friends GTX 560ti performs flawlessly. He has a better CPU but I thought that GTX 770 would be alot better than GTX 560ti. Anyone else having similar problems wit GTX 770? It's very frustrating that I paid over 300 euros for this card and an older card works much better than my new, shining GTX 770...

Nope, it's not just me, there was a big difference when we played with my friend, his game worked perfectly. He has a more powerful CPU so that might affect his games. His GPU is weaker than mine but it's 560ti so it's quite powerful still.

For 1080p single screen. Yes it is. No joke. But your 770 should be WAY faster if running right.

[Ted Snark]

I know, right? It should be faster and still it gives jerky performance in older games, newer games are fine for the most part. One option is that my hard drive is so weak that it affects the performance of games.

rad87gn, I use CPU-Z at the moment for monitoring. And as I said, newer games seem to work fine without much problems, it's the older games mainly that give me trouble.

If CPU-Z is right, my clocks are 1188 mhz in game and only 135 mhz when idle.

What I've seen in the internet it seems that quite a few people are having stuttering issues with GTX 770...Even when their FPS seems to be fine.

Hmm, I noticed that my GPU usage is nowhere near 100% when gaming...Is that normal?

And I'm going to repeat myself I have the same processor and graphics card. I never experienced any issues in games due to my hardware.

I've experienced no slowdowns or stuttering in Borderlands or Borderlands 2 two games you said you have trouble with.

Do I know your issue? No.
Do all people that have a FX-6300 and a GTX 770 have your problem? No.

[Ted Snark]

I'm sure that not all people who have the same CPU and GPU have these problems, there could be something else, like my hard drive which is quite old. I might be swayed to believe it's just me if I hadn't seen with my own eyes that my friends weaker GPU runs games much better than my GTX. So, either the card is faulty or my hard drive causes these problems.

Borderlands 2 has actually little overhead. I can max it out on my crap laptop with a GT 650m. Get to the problem. It's not found yet.

The game itself has little overhead. With full PhysX enabled I managed ~30-40fps with a 650Ti myself (and a Core 2 Quad Q8200). Using a GTX770 (paired with i5 3670k + 8GB DDR3 @1866) I'm getting 50+fps at the same res (but not a stable 60). So it's not the card as much as the game engine in that case I'd guess. The 770 destroys the 650 in terms of memory, processing power, the works.

[Ted Snark]

Yeah, newer games work pretty much as they should, BF4 was smooth like butter. I've played years old MMORPG's and single player RPG's that are jerky and stutter like hell.

[H3X]

It could be threading with the cpu causing a bit of a bottleneck as was mentioned by Rumplecrutchskin when it comes to older games. I've a fair few myself that are borderline worse using a cpu with more cores as they weren't optimised for it at all.

Supreme Commander is a great example, actually. That game is optimised for single core, because when it came out multicore processing was still new and noone was sure which would be better. If the card is performing fine in benchmarks and there's no PSU issue then it does look like something else, and that is a possibility.

[Ted Snark]

Yeah, even some newer games are optimized for fewer cores, like Guild Wars 2 for example. And Neverwinter Nights 2, which is an old game, stutters also. Not much, but still. It's funny that a brand spanking new GPU does worse job with older games than older cards. But, I'll just have to upgrade my CPU at some point and maybe my HDD too.

[H3X]

How old is the HDD and mobo though? If they only supports SATA2 rather than SATA3 then the data transfer rate is effectively halved, which could only add to any bottleneck for the GPU. EDIT, I should ask, make and model for them too.

[Ted Snark]

HDD is from 2009 and my mobo is M5A97 LE R2.0, so HDD is quite old.

[H3X]

Hmm, motherboard is SATA3 capable so HDD/CPU would be the biggest limiting factors if it's a bottleneck from the look as a mobo fault would usually be pretty apparent. HDD isn't Seagate is it? I've had some bad experiences with those in the past. (though ironically using one for my Steam library now lol).

[Ted Snark]

No, I don't think it's Seagate. I have an outer disk drive too, but I don't know if it's faster or not. Many have said that my CPU is the bottleneck, and my firend, whose PC runs games better than mine even though he has a 560ti, has upgraded his CPU to FX-8000 series. So my CPU might be the culprit here, as well as my HDD...

[H3X]

Well your motherboard is capable of 6Gb/s transfer as far as the specs state, whether or not your HDD is too depends on exactly what it is. Even so, it probably shouldn't cause such a huge difference though as far as I know. I'd google the product Id to check personally, in that regard.

I run a Core 2 Quad (+GTX650Ti) on an SATA2 board as a second machine and it doesn't stutter like that in older games unless they're heavily modded or pretty poorly optimised usually. There's always exceptions of course I guess.

EDIT: an external drive will always be limited by the transfer rate the port it's plugged into is capable of by the way. So if it's USB, it's likely slower than an internal disk by a pretty big degree.

[Ted Snark]

I was shocked when I played Drakensang The River of Time an the first battle seemed to slow thing down. It's a pretty game but not that pretty that it should destroy framerate with such a powerful GPU. And I haven't seen any big difference with my older HD6870 compared to my GTX 770, which concerns me a lot...At least not in older games.

[H3X]

The 770 is basically an upgraded 680 so yeah it should hold its **** pretty well lol. Then again older games only thread as much as they're programmed to, there's a point that all of them will fail to perform better on better hardware, somewhere with multicore being the norm nowadays. Until devs start coding for multicore (as in 4+) properly, that will likely happen down the line to almost anything..

^Should help you bench your HDD, though you may want to look up expected average transfer rates for the HDD to check against your results.

^This can help you check your CPU is running at the correct settings, though you might want to bench it properly at some point to make sure it's not on the way out.

I'd also recommend Memtest to check your RAM, though that might well be fine from what you've said. A good test with that can rule it out pretty much entirely.
