was just using the 4x that came with the profile, ill try some other ones and look at the indicator if i can get around to it but its not a huge issue for me cos i like my games smooth without aa most of the time anyway

I have the same slowdown reported by you and user moop1167 on the nHancer board. Something is definitely screwy just got to isolate (if possible) what's going on. Without the profile for ME2 the game is 60fps (vsync always forced on here to prevent run-away framerates that encourage board overheating for no purpose.)  but with the profile active, fps drops from 60 to 37 and stays there when exiting the elevator into Engineering deck staring out the windows to the equipment. The default here is (correctly) set to 4Way AFR due to the set up but I'll mess with that too once I start to fiddle with it and see if can cause any increase in performance -with- AA enabled.

Relevant configuration:
Vista U. x64
Intel i7-975 @4
2xGTX295 (186.18)

go into mordins tech room bro, thats where the lag is. (and everywhere else)

its not AA or AF. its enabling SLI in nhancer that causes the lag :/

[biglerman]

very nice work ;D

[eclipsez0red]

maybe thats why nvidia pulled SLI support from the 196.34 because of people like me getting these slowdowns



but sli seems to be working when i play me2 without using nhancer.... both my cards are burning hot, and i literally mean burning

UPDATED: See latter section. It's the shadows...

Yes as I said I just started messing with it. Have built some graphs with various modes and settings so far. Using the Engineering Deck with a quick save staring straight out the elevator doors through the windws is good enough for testing modes in this manner.

My results over the last 30 minutes show SLI is clearly the problem. I have zero doubt that nVidia and/or Bio will find the issue and correct it, or damn well hope so. To bad we can't get inside info on what cmpatibiity bits do what from nVidia if we did that would help a lot because we could probably just use good logic and stop having to guess.

But at any rate the following shows SLI = kablam:

Using the Engineering Deck windows straight out the elevator:
nHancer:
SLI Mode: 4WAFR
60fps: AA Off
49fps: 2AA(MS)
37fps: 4AA(MS)
45fps: 2x1(SS)
45fps: 1x2(SS)
27fps: 2x2(SS)
31fps: 4xS(CS)
22fps: 8xS(CS)
SLI Mode: 3WAFR
41fps: 4AA(MS)

SLI Mode: Single
60fps: 4AA(MS) <---

UPDATE:
It's the shadows + AA + SLI 

Game Config:
1920x1200
HQB: On
FG: On
MB: Off (hate MB)
*DS: Off
LES: On
NCL: 3
USHL: On
AF: 16x

SLI: 4WAFR
4xAA(MS)
60fps everywhere regardless.

*DS: On
kablam... 30's / 40's.

Based on what I'm seeing through the windows, the shadows themselves (on the floor for example) are being heavily AA'd / look ultra smoothed. This is not the case with shadows from the character on nearby structure, such as the floor underneath us or wall behind.

So maybe it's the way the shadows are processed on reflective surfaces, which describes the floor seen through the windows of engineering. I'm not a game developer / DX expert but I'm sure we have some roaming around (either staff or another member) that could chew this at a lower level and probably explain why. Since it only happens with SLI on that seems to indicate to me it's the way shadows are processed in the streams and being split or slammed across different boards when SLI is going. Since the shadows themselves appear to get extremely smoothed perhaps the same shadows are being incorrectly rendered again per-board when they don't have to?

So at this point, it's either AA w/o SLI, or AA w/SLI but no shadows.

[IKe0s]

The "stutter" you are reffering ( on specific location ) is produced only after you access the MENU-UI. So, Scaleform fault.

Workaround.
Place those file in your "\\\\Mass Effect 2\\\\Binaries"

Binaries Helper

Otherwise, if that didnt help: once u notice there some stuttering ongoing, check both's core clock. If some are in idle perhaps you should set "adaptive power management" to max performance over the Mass Effect II profile in the NVIDIA control panel.

good job

[moop1167]

Yup, Iron thanks for taking the time to post that out. This issue seems to be plaguing a few others on some other forums I post on as well. It seems that SLI and AA together cause these slowdowns in certain places. SLI with no AA on = good fps. SLI off with AA on = good fps. Both? Terrible. The funny thing is that I get great fps in a lot of places but places like the engineering floor and the lab outside of the Illusive Man's office they suddenly drop. Turning off dynamic shadows something I really don't want to resort to to be able to use SLi correctly. Hopefully they look into finding a solution for this.

[mr_luga]

Im not a tech person im confused.. What exactly does this do? Or a better question.. Why do I need SLI?

[moop1167]

I wouldn't worry about it, it's for people that have two video cards in their machines.

[LogicalDisconnect]

I can confirm that turning dynamic shadows off fixes the problem for me. Not really an acceptable solution, though. Hopefully someone finds a fix; the game looks much better with AA, and runs much better with SLI, but the two together just don't mix!

[digitalforceq]

Strange.. I have a GTX 295. I removed the SLI part of the NvApps file but kept the AA settings and 4x AA + shadows and everything is butter smooth! W00t! I was getting slowdown with the SLI AND AA settings before.

[LogicalDisconnect]

So you're now just running with AA and without SLI? As I mentioned, that seems to work fine. But you obviously lose the performance boost that SLI provides. For example, I only have 8800 GTXs, and with 4 x AA and no SLI my framerate isn't really acceptable, though it probably would be with a more powerful card like yours. So turning off SLI and leaving AA on isn't really an ideal solution for someone in my situation.

[digitalforceq]

Yeah, I can't believe how well it runs.. without SLI. Will test more..

[Grestorn]

It's not consistent, though, because I myself and other people (see the thread on the nHancer forum) can play ME2 with SLI and AA (and dynamic shadows) just fine.

[LogicalDisconnect]

Yeah, it's really strange. My [SystemSettings] section is identical to yours. I also saw the specs you posted on the nHancer forum and nothing stands out as an obvious difference between yours and those of the people having trouble, other than the specific videocards. But from memory people have been having problems with cards of all types, ranging from 8800s to GTX 275s. So I have no idea what's going on. I've downloaded a few older drivers which I'll try later, but I can't think of anything else to do!

[eclipsez0red]

i got the lag with



2 x gtx295

i7

vista 32bit



nvidia will be working for a fix on this you guys.... but as you know you wouldnt expect another driver release from them for at least another 2 weeks

[moop1167]

Temporary fix is to use compatibility mode 08020205 for AA. It reduces the lag in the normandy engineering room and those troublesome places a little bit, but it's not perfect. Instead of 20 fps in those areas it's up to around 40-50, which is acceptable until they can get a fix out.

That's it;)

I got it working via nhancer as well, but im using 00000045:  AA & HDR mode.  It works and I even had to turn down the AA to 2X2 - supersampling, because the 4x4 slowed my frame rate down considerably.  Ill give your mode a shot to see if there uis a difference.

[Spawnyguy]

Can someone tell how to enable nHancer when I run ME2? Can I use nHancer with a 9800GTX+ using driver ver. 196.21? I've tried playing around with it but it doesn't seem to enable any aliasing to the graphics using the recommended ME2 settings. I'm new to using this type of program to enhance the game so if someone can explain what I have to do would be appreciated thanks.

Go to the engineering room in the Normandy and see if you get huge drops.  I have great fps too except for in certain areas... it's a definite bug.

[LogicalDisconnect]

Just thought I'd post that with the default profile, I seem to be suffering significant lag in certain areas with SLI on even without AA. The most obvious at this stage is the opening cutscene, where I get about 15-20 fps with SLI with and without AA. I can improve things by setting the SLI compatibility flags in nHancer to be the same as the flags for Mass Effect 1, but my performance is still no better than for a single GPU. So SLI doesn't really seem to work at all for me. The only solution seems to be to turn off dynamic shadows, but that's obviously not ideal.



If anyone has any ideas, I'm all ears!

[ChandlerL]

Re: those of y'all not seeing performance gains, have you verified that SLI is, in fact, working for you at all? For instance, turn the SLI Load Balancing Graph on and see if you're getting an even spread of bandwidth.
