Low FPS in Source games with GTX 560ti

PC specs:
Intel Core 2 Quad Q6600 OC @ 3.4 GHZ
EVGA 780i Mobo
4GB Corsair XMS2 DDR2
Corsair 750 watt PSU
EVGA SuperClocked 560 Ti 1GB
Windows 7 Ultimate 64 bit - Service Pack 1
Driver: nvidia 275.33

I just bought a new EVGA GTX 560 ti to replace my evga 8800gs. Before upgrading I could max out all source games with 75 fps all the time with vsync enabled. However the 560 gets terrible fps in the low 30's and even the 20's at some points.

I mostly play left 4 dead 1 and 2 but the problem is apparent in all source games.
Settings: 1440x900 all settings very high-high 4xaa 16xaf
L4D2 running on 8800:
CPU USAGE: 50-60% GPU USAGE: 90-95% FPS: 75-60(with vsync)
L4D2 running on 560ti:
CPU USAGE: 95-100% GPU USAGE: 20-30% FPS: Drops into the 20's-30's(with and without vsync)

For some unknown reason Source games seem to only be using my CPU now and not putting any of the load onto my GPU.
I have uninstalled and reinstalled my drivers using driver sweeper multiple times, flashed my bios, reinstalled windows 7, overclocked and even down-clocked my CPU to stock speed, nothing helps.
Nearly every non-Source game I own runs fine with my 560ti. I can play BF:BC2, Crysis, Crysis Warhead, and Metro 2033 all maxed with very good fps. My CPU was more than capable of running source games when paired with my 8800. Does anyone have any idea what could be the issue?

At 14 x 9 the GTX560 is barely ticking over so the load will shift to the CPU so if those game are not GPU intensive then the framerates will be affected.

So I will get worse performance with any new card on the market? I have been dealing with this issue for 2 weeks and no one could give me a real answer to what was causing it, even evga tech support. I was planning on sending it back for an ATI 6950 but I don't know if it will even help now if what you say is true. My friends have 260gtx's and 9800 gtx's and max out source games flawlessly some of them run at 1440x900 and some at 1920x1200 and have no issue. However my other friend is running a 6870 at 1024x1200 and he isn't experiencing any dips in performance in source games at such a low res. Is there anything I can do to force more gpu usage out of the card. I tried cranking up aa but the performance is the same no matter what...

In my experience the newer cards don't always perform better with older games but they do tend to perform better at the higher resolutions than the older cards.

I recently built a new pc for a friend with an i7 2600k and non ti 560. I tested L4D2s performance on his system at 1024x1200(he didn't have his new monitor yet) and it was averaging around 300 fps constantly in a versus match. After seeing that kind of performance I decided to upgrade my card. I guess all of that performance was due to the 2600k?

So basically there is nothing I can do? Do you have any suggestions? I am really disappointed that I paid 260$ for a new gpu and it runs the games I play the most worse than the card I've had for 4 years. Do you think switching to an ati card would have any benefit at all?

You can do that if you want, I would never spend my own money on one though but if you think it'll make you happy then go for it.

Yeah personally I have always preferred nvidia over ati. I have experienced a lot of driver related issues with ati in the past. I just don't know what other options I really have besides building a new i5 or i7 rig or possibly getting a monitor with a higher native res.

I tried my 560 on my dad's tv @ 1920x1080. It did boost my fps but I was still getting drops into the 40s and 50s during large hordes. Shouldn't I be getting better fps than this?

I ve got about the same problem, good to hear i'm not the only one. I began to think i was imagining this problem because i got almost no reactions on my threat about this topic.
I went from gtx 465 to also a 560 TI ( soc version gigabyte ) and the 465 performend better i think in some games ( company of heroes, rise of legends ) so what the ... is wrong with the 560 especially because the difference between a 465 en a 560 is less i think then the difference between your old card and a 560, but still we have the same problem. I'm playing on a 1920 x 1080 monitor and an i7 870, 8g. Weird.

robjordy are you experiencing fps drops in source games or are you just getting lower performance in the games you listed? Most games I have tested run much much better on my 560 ti. Only source games seem to be having issues. Like I stated in my previous post running at a higher resolution seemed to help some but I am still not getting the same performance as my friends who own 9800gtx, 260gtx, and HD4870. They never dip below 100 fps in these games.

I have a question. Often time people who get new video cards get excited and turn up all the settings to max. Often times these settings put more stress on the CPU as well, or are settings that are still just extremely demanding.

Did you change your settings at all? Having a longer clipping range would stress your CPU a lot, for example.

No, my settings are the same. I bench marked L4D2 on my 8800gs and my 560ti. My 8800 got an average of 10 more fps and did not suffer from any fps drops.

Good one. I have really no idea of the games i'm talking about are source games.

If you aren't experiencing fps drops in Source games we don't have the same problem. (Source games: TF2, L4D 1&2, CS:S, HL2)

No as I stated in my first post I can run BF:BC2, Crysis, Crysis Warhead, and Metro 2033 all maxed with 4xaa with very good frame rates. This issue is only with Source games.

I've seen similar posts from AMD users, although they didn't have as bad of results as you are getting, they didn't get the results they expected either. I wonder if you setup a dual boot with XP, it would perform better with these source games.

Maybe, I just don't really want to do that. My 8800 never had any issues running these games on seven why should a new gpu?

Why don't you just go back to your old card?

You could try right clicking the Game shortcut and turning on XP compatibility mode.

My specs

Intel q6600@3.54
4 GB OCZ reaper
4 GB Corsair XMS2
XFX 780i SLi
Gigabyte 5606Ti OC (have two running in SLI)

First thing I would do, is try to download the Heaven Benchmark, and check your total score. Post it back, and I will compare it with my results, i will have to disable my one gpu, but what the hell. i know in crysis my benchmarks are pretty low, but in crysis 2 and all other games, they are going solid 60 fps and higher.

Yeah, I was considering that option. I already called newegg a few days ago. Basically if I want to send my card back for credit so I can purchase an ATI card it is going to cost me 40$+shipping for re-stocking fees...I just wish I could figure out the issue so I don't have to spend money I could be using to upgrade other parts of my pc. :(

My CPU is oc'ed @ 3.00GHz currently (I don't like to run it at 3.4 all the time because of high temps) but here are the results of the Heaven Benchmark. I will re-run the test with a higher CPU OC later if you think it will provide more accurate results. http://filesmelt.com/dl/Heavenscore.png

Great, not that atleast shows that there is clearly a bottleneck for your performance. I myself had a bottleneck at 52 fps when i ran with the exact same settings as you. The only advantage you have over mine is that you have a much higher clocked card. Now that clearly tells us that it is not the gpu, but the game support itself for the games that you are playing. Increasing the oc of your cpu would only benifit if you want to play on 1080p resolutions, and the bottleneck would drop to almost nil. I do not have a left4dead benchmark tool, but would have benchmarked that as well just for an apples to apples performance test. I would only recommend trying a local pc store and getting a 1080p monitor, then running the heaven benchmark on it at full 1080p maxed out. there is nothing to lose as you can return the monitor/tv, but you will know that it is not the GPU. Once you have put up your scores for the heaven all maxed out on 1080p, we can match the scores and it will give a better understanding of your issue when there is no bottleneck. i do recommend oc your cpu to 3.4 when running the heaven at 1080p

A guy from the evga forums is helping me with my issue now. I'm testing out a few of his ideas and they have increased my fps greatly. My game feels much smoother now but I am still getting the random drops. I'll let you know if I figure out the problem. Thanks.

The issue isn't completely resolved. I am still getting frame rate drops but they are occurring less frequently. Windows update had installed a default driver over top of my nvidia driver even though I had updates disabled. I removed it and reinstalled my drivers. This smoothed out the jerkiness of the game. I am still not for sure why my fps keeps dropping. I could shoot my gun and I would drop 30 fps. Now I seem to only get fps drops in large hordes.
