Is Nvidia still better for pcsx2

[StriFe]

sorry that my text seemed a bit well annoyed lol, I was just awake then hahaha. But yeah I hardly had any issues with the drivers, well I had one issue with 11.10 till 11.12 with my monitor and games. My Samsung (Happened only with samsung monitors apparently) said not optimum mode 1920*1080@60. Now with 12.1 preview I don't have that issue anymore

I hate to bump older threads, but I have had a HD4850, 6950, Gtx 480, a 570, a 580 and now a 7970 [dont ask why, long story]. In Dragon Quest 8 @ 2000x2000 internal res and 2x AA this is the average I got on each card, in the first town with most of it in view [the first town hits your FPS harder than most areas in game]...

4850- 3-7 fps [512 ram on the card, looks like thats why it was hit so hard]
6950- 28 fps [1gb ram on this card, ram hit again, 2gb should be much better]

480 [overclocked to 920 core] 83 FPS
570 not overclocked - 66 FPS
580 @ stock - 78 fps
580 overclocked to 870 core - 82 fps
7970 [overclocked to 1000 core- 72 fps

What I see - 1.5 GB of video card Ram is the minimum for the best results in Pcsx2 @ 2000x2000/2xaa. DQ8 at a high internal res chews through ram like nothing. The 570 has 1.2GB and it incurred a larger fps hit than it should for its speed, so RAM issue there imo. The 7970 lags behind even the 2+ year old 480 in this emu, and it has 3GB of Ram so that is not the issue at all [480 has 1.5GB]. Id say a 560ti is about even to a 7970 for Pcsx2 overall, and for much less money [of course a 7970 owns it in everything else].

Nvidia is definitely at a advantage here, cards that are 2 generations older are faster. The exception is if you go to obscene internal res's like 3000x3000 then the 3gb of ram on the 7970 will make a difference, but your fps wont be above 60.

O.o I'd love to know the details of these tests, because I myself have a 6950, and I maintain a constant 50 fps (PAL) on DQ8 @ 4096 res, albeit it's the 2gb version, but still..

I think your CPU counts more heavier then the Graphics Card does

And that's not the point of those test. Congrats for missing them.

Hmm, I wonder if the reason why I can't run Ridge Racer V at full speed at anything over 2x internal res, is because of the 1GB video ram in my ATI 5870? Does video ram make a huge difference when cranking up the internal res in PCXS2?

Sorry, i researched the 6850, so thats a my bad.

Anyway, back when i had my ATI card (again, this was 05) i had games that didn't work/run as well strictly cause it was ATI. (for example, knights of the old republic)
Cause of it? Well at the time, it was ATI's horrid drivers. They have since been purchased by AMD, whom i like. So maybe they'd gotten better. but back then? they were horrible.

Nvidia all the way,

ATI/AMD don't really do this,

Nvidia =win

I think the problem with ATI cards is still that the driver puts up more CPU load than Nvidia does.
It's a hunch though, not actually verified yet.

The details do matter, I can share the save state that I have so you can check it out yourself.

A pic of my settings -






*My Vcard is not overclocked in that pic, think my MSI Afterburner expired [just noticed it but shouldnt matter to much].


Window screen size is at 1080P, internal res 2kx2k / 2xaa. I also have AA in my Catalyst driver set to enhanced AA but I dont believe it overrides anything in Pcsx2.

My system specs-

i5 2500k @ 5ghz
8GB ram
Asrock Extreme 3 gen 3 motherboard
HD7970


The low FPS I get in DQ8 is only a worst case scenario, I went out of my way to find a good spot for it since I enjoy DQ8 and it is also easy to test + does stress video cards [farrrr more than it should]. In normal play Im sure the fps would be 2x to 3x higher 90% of the time.

From my experience it does, when you are not video card memory limited in Pcsx2 your fps will drop linearly with resolution [if you are using the same settings for both internal resolutions and IF it is your video card holding your fps back].

If you have 50 fps@ 512x512 [vcard limited here as a example to keep things easy], going to 1024x1024 should cut your fps to 25...If it drops more than that, drastically especially, you hit a video card ram wall. On the 4850 DQ8 was very playable at 970x970 with 2xaa for me, but pushing it to 1200x1200 cut the fps by a obscene amount, atleast a 4x fps drop. 2kx2k was just not playable at all.
