Eyefinity - High FPS, still feels sluggish.

Jarrod · 13 Apr 2012 at 04:52

Even when running at constant 60fps, it feels sluggish and acts as if it has 28/29fps, Vsync makes no difference that I can tell. Playing on one monitor at the same fps is absolutely silky smooth, but when Eyefinity is enabled this happens.

Is this normal? Is there a fix? Optimizations?

This is in every game by the way.

Using 12.3 with 12.3 CAP1

12.4 beta makes my eyefinity desktops glitch like crazy.

Heeeeeelp!

Thanks in advance!

Microstutter my friend.

I had a 6990+6970 combo with Eyefinity and when playing BF3, it felt sluggish due to microstutter. It was only 'fixed' with the 12.1 drivers. I suggest playing with one monitor without capping FPS would lead to >100fps where microstutter isn't an issue really due to the high fps. But running EF with 2 x 7950s, you'll feel it

Have you tried fixing the FPS to something like 52 with MSI AB? Try it and see if it works

I would suggest you have to wait for a decent driver set

Try turning off Windows Aero aswell. With crossfire you need ~75 fps to make it feel like 50 fps from a single card. Drivers do play a big part though so I'd suggest playing around with different ones.

I eliminated microstutter completley by enabling vsync.

I found xfire and eyefinity a right pain, my games played better on a single 6970 than they did on two,the best set up i had for eyefinity was with a 7970 but that was proberly due to the 3gb of ram

Tried Vsync and fps capping, didn't help unfortunately. Guess I'll have to wait for some decent drivers.

i know you are getting 60fps but what are your settings in bf3?

try lowering some

How i removed microstutter and input lag from bf3.

Use vsync.

user.cfg file

RenderDevice.TripleBufferingEnable 0
RenderDevice.ForceRenderAheadLimit 0
MaxVariableFps 59

Disabling triple buffering removes lag when you aim down the sight and sidestep.

BaDBoY_uK · 13 Apr 2012 at 20:39

Try forcerenderaheadlimit 1

Also try looking at these

LtMatt · 13 Apr 2012 at 20:59

Interesting badboy, im pretty sure its different for two card crossfire. Do you have any graphs for that? Id be really interested.

Will try this now

.

Also, even if settings are set to low in BF3, it still feels sluggish despite ridiculous FPS.

I would argue it is the same mate. It is crossfire issues. I suggest renderaheadlimit 1 for crossfire and trifire rigs - see here

It is microstutter mate. Try displaying the graph and switching between ahead 1, 2, 3 and 0

Jarrod · 14 Apr 2012 at 00:08

Sorry completely missed your post badboy, will try that also!

Jarrod · 14 Apr 2012 at 02:36

Ok the suggestions made by badboy and LtMatt seemed to make the experience much more acceptable

. Thanks guys

Yeah 1 does seem to remove some micro stutter for me, its small but noticeable. Thanks mate, quite tempted to try 2 out as well.

edit

2 was worse.

Another thing you could try is get the latest MSI Afterburner Beta, and use the frame rate capping feature to cap the max frame rate to 55~60fps. I recall people with crossfire mentioning the micro-shutting issue is reduced by using this method.

Using an ingame fps cap would be just fine, right?

chipachap · 14 Apr 2012 at 23:02

Try -1 or 1 for the render ahead limit and enable triple buffering for sure, helped me in BF3 a good bit. The in-game cap should work perfect.

Probably, but if you use MSI Afterburner to do it, it will apply for other games as well, not just BF3.

MeMeMeMe · 15 Apr 2012 at 03:23

Can't you set the ingame cap for each individual game, in MSI Afterburner?
