HD7950 - amazing in BF3 but stuttering in Counter Strike GO and simpler games

post #1 of 10
Thread Starter 
Hi all,

I have managed to get my Sapphire Vapor-X 7950 OC with Boost humming along amazingly in BF3. I can run everything at ultra, low/medum post a-a and HBAO and hit a consistent 76 FPS in most situations with vsync on. It's the same if I use the more traditional 60 Hz vsync settings. Everything is buttery smooth like never before. My problem is, that there are few quirks with the card which irritate me to no end - which I never had issues with when I was using my GTX 570 (although that could not overclock well and eventually started crashing all the time at stock, I think because of the VRM dying since more voltage made it worse). One thing I can't live with is the fact that many other games have an issue where while the frame rate is maxed out, the actual game play is difficult because of a major laggy / jerky / stuttering issue. In fact the situation is *worse* with games that aren't demanding, even if I turn my overclocks off.

First of all, my setup:
Motherboard: Gigabyte Z77X-D3H @ 103 MHz BCLK
CPU: Intel i7 2600k @ 4.634 GHz (x45 multi, +.75v, medium LLC)
RAM: Corsair Vengeance 8 GB @ 1648 MHz (Turbo LLC)
Video Card: Sapphire Vapor-X 7950 OC Boost @ 1.3v 1200 MHz core, 1.6v 1700 MHz meomory, +20% board power, (MSI Afterburner 2.3 - force constant voltage checked and UnifiedMemoryUsageMonitoring = 1 in cfg file, Catalyst 2.11 beta - Enable Graphics OverDrive unchecked, Radeon Pro 1.1.1 – flip queue 0 in global settings, BIOS 015.025.000.099)
Monitors: Dell 1097FP (Connected by DVI-VGA converter as its DVI is not working, 1280x1024@75 Hz Samsung BX2440 connected by DVI. ToastyX’s CRU tool used to force 1920x1080 refresh rate @76 Hz

So in Borderlands 2, I noticed things were particularly jerky, unless I used flip queue 0 (similar to render ahead limit 0 which I have a cfg file in battlefield to force, along with triple buffering disabled) and set max framerate to 72 FPS (full screen windowed mode has a similar effect). The new catalyst 2.11 beta also helped. But in Counter-strike source and Counter-strike GO I can’t get rid of the stuttering despite 300 fps. The switch -fps_max 76 helps but doesn't get rid of it. It’s sort of like the card is getting gummed up producing gobs of old frames, but at least in CS:GO the core doesn't drop to 875 Mhz because it thinks its idling. Deus Ex Human Revolution, AvP and Star Craft II all work buttery smooth though.

The other issues are that I want my monitors to turn off after 15 minutes, but even if they do the monitors usually turn back on, but are blank (the backlight is producing light though and it is not blinking like it should on standby). Sometimes the I even see just the mouse pointer on the blank screen. Similarly, if I change to single monitor mode, the second monitor gets polled from time to time or something and the backlight turns on. At night this means the monitor looks like its flashing grey from time to time (maybe a minute or two between flashes) which is annoying. Lastly keeping an OC is difficult. If the memory clock is changed at all, no matter what the settings (even in Trixx 4.4) the voltage will stop going back down on idle and will stay high. Not so with the core clock. Force constant voltage has to be enabled otherwise the voltage won’t respond at all, so basically at all times the voltage reads 1.3v. Every so often the clock will just start jumping around wildly, and I will have to check apply and uncheck and apply overdrive in CCC then reset in MSI and load back my configuration to get it staying at 1200 MHz in games. I’ve run into a new problem recently where if I load any OC profile, the clock will start idling at 300 MHz instead of 500 MHz and I will get artifacts all over the place when anything on the screen moves (I think it’s possibly the commensurate drop to 150 Hz memory clock that is the culprit). The solution to this is briefly switching to dual monitor mode so when I switch back it stays at 500 MHz idle and the mem clock goes back to 1250 default or 1700 MHz if on OC.

TL;DR, the 7950 is more amazing than the GTX 680 when OC’d to 1200/1700 hardware wise (Pixel Fill 38.4 GPixel/s, Texture Fill 134.4 GTexel/s, Bandwidth 326.4 GB/s) and kills everything in BF3. But I have to hack at the drivers and game configuration constantly to make everything actually work, and still some basic games are stuttery and there are niggling bugs.

Use an fps limiter?

VSync should do that, and fps limiting didn't work in-game or through Radeonpro. However, after switching 'boost' button off on the Sapphire 7950, installing Catalyst 13.1 beta, and using the switches below in CS:S, the jerking is gone. The switch got rid of the residual fuzzyness when I was looking around, must be a mouse related problem that you can't see at lower refresh rates:

-dxlevel 98 -useforcedmparms -noforcemparms -noforcemaccel -heapsize 4194304 -refresh 76 -noipx -nojoy -fps_max 76 -m_rawinput 1 -m_filter 0

Dxtory seems to be the only thing which when limited to my monitors refresh rate can help Skyrim stop being stuttery (especially when I look at the floor and strafe for some reason) but Borderlands 2 still stutters like crap, it looks like it's doing 20 fps but reports over 72 fps in any scenario. Do other people with 7950's find this issue?

My friends 6770 does this in CS:GO. His ping is 90 (hes west coast to my United kingdom), and gets like 7-8 fps (or it would seem that way, atleast)

I have been searching for a fix for a long time and cant find one.


Last ditch effort is to use RadeonPro

13.2 beta drivers due this week address frame latency issues in skyrim and borderlands 2. so grab them when they release. there is a leaked 13.2 beta which many users are already using and have reported improved frame latency. but you can wait for the official beta drivers as it has more fixes.

I never had issues with skyrim and B2. Very odd. Anyway, can't wait for 13.2b

Wait I'm curious, but how exactly did you disable the boost? I would like to do that too.

I've tried using 13.2 and as far as I can tell it solves the lagging issue in Skyrim but not in B2 for me or CS:S. I noticed the key fix for stopping CS:S stuttering was to force DirectX level 9.5 or 9.8 (and dropping the polling rate on my G500 to the default 500 MHz). There is a way to force Borderlands 2 to use DX11 in the Willowengine.ini, but it still is really choppy full screen, though combined with 13.2 it makes windowed mode it's a lot smoother (but then slows down a lot during firefights anyway -not sure if this is just a general issue because lots of people have fps drops during fighting and windowed mode is less efficient). So I think there is just some kind of frame-rate or pre-rendering issue that creates a bottleneck in this game. Underclocking/overclocking doesn't seem to help - the best balance is about default clocks but I still can't play the game because it feels like I'm playing it on a 10 year old machine.

I just turned off the boost switch on the card (it lights up blue). It doesn't do much if you've disabled CCC's overdrive and are using Trixx 4.4 beta to control the clock in terms of performance I find (it's just a bios with different defaults). The only difference to me is my memory voltage doesn't drop back down if I reset the OC in Trixx (I have it about 1.537 mv 1675 MHz when clocked up, with the core at 1170 MHz). I think the boost bios still causes MSI Afterburner a few more problems but I haven't checked since upgrading to CCC 13.2 since I only use Trixx now.
