I recently picked up Quake again after some time and I have not been able to resolve this issue. In-game Video-Lag (Input lag). I attributed this 'floaty, squishy and delayed' feeling to the fact that I haven't played in so long I figured these were the new physics of Quake Live in comparison to Quake 3. I'm a veteran of Q3 so I have a good understanding of how it 'should' feel. Thanks in advance for any help on the matter.
Here's the problem:
I experience a 'floaty and squishy' feel when moving around the map. When jumping, it almost feels as if I'm jumping on the moon with limited gravity. It seems that all movements are slightly delayed, as well as other player's movements. In fights, it feels as if I'm several frames behind as I can never get the first shot in and I often wake up dead not knowing what just happened until it was too late (Yes, enter your jokes here). Keep in mind that this problem also occurs when I launch my own practice game. This is not an Internet latency related issue nor do I believe it's a mouse-lag issue. Its undoubtedly a video rendering/lag issue.
Out of curiosity, I launched Quake 3 and the problem was gone. There was no delay and all movements happened instantly without delay. Shooting rockets came out quickly as opposed to feeling as if I have a 150-200ms ping. Then again, this is Quake Live, not Quake 3.
I have tried several things to fix the issue, so if you can offer a helping hand, please look over my system specs and the things I have tried to resolve this unbearable video-lag issue.
Gigabyte Z68MA-D2H-B3 Motherboard
16GB DDR3 1333MHz
AMD HD Radeon 7850 (Fairly high end card and it runs everything else without issue)
SSD 248GB Hard-drive (I have all APPS and Games loaded on this drive. Data on a 7200RPM Drive)
For gaming, I use the built in sound and disable my Pro Audio card which I use for music production related tasks.
Logitech G9X Mouse
Asus VG236H 120hz 2ms/GTG LCD Monitor (Yes CRT is better, but this LCD is great and doesn't produce the same lag in other games)
Windows 7 x64 (BLAH)
Over the span of a month or so, here are the things I've tried:
1) Downloaded RadeonPRO and forced Vsync off, forced Flip Queue to 0 (Pre-rendered frames), turned all graphic related settings to high performance, forced most filter settings off (Anisotropic, tessellation, trilinear, etc).
The above helped quite a bit and eliminated a huge chunk of the video lag I was experiencing, but a noticeable amount remained.
2) Applied mouse acceleration fix to give a 1-1 ratio and ensured 'Enhance Pointer Precision' is unchecked.
3) Tried several different polling rates, 125, 250, 500, and 1000. I settled on 1000, but this did not eliminate any noticeable lag for me.
4) Ensured all Window's power settings are set to maximum (USB, CPU, PCIe, etc). No, I'm not connected through a usb HUB. Tried using different USB ports, 2.0 and 3.0, no difference.
5) I play through QLPrism (Quake Live launch application so it plays as a dedicated application and not through a browser. I also tested different browsers (Firefox, Chrome, IE) with the same problems.)
6) I changed priority of Quake Live to HIGH and also Realtime with no noticeable performance boosts.
7) I tried launching QLive with XP SP3 compatibility selected but to no avail. Even tried to run the game as administrator but that actually increased video lag.
8) Disabled many unnecessary Window's Services. I don't remember all of them but off the top of my head: Windows Event Log, Desktop Windows Manager Session, Window Media Center Sharing related services, and some others I can't quite remember.
8) Tried playing through VGA connection from DVI (Dual and single link cables). Same result.
9) Even tried game booster, but this didn't make any noticeable changes.
10) I have a quad-core intel processor and have heard that many older games don't work well with Quad-core processors so I tried different window's affinity settings: Tried settings QLive to utilize only 1 core as opposed to 4. I also tried setting affinity to only 2-cores for QLive, but this did not make any difference.
11) Formatted my system and reinstalled everything from scratch. Same issue.
12) Uninstalled video drivers (Sapphire HD 7850 drivers, along with Catalyst drivers) and reinstalled. I also tried different driver versions, but the video lag was still there. I used driver sweeper when switching between different driver sets/versions.
13) I tried two older video cards: MSI HD 5770 and HD 4350. Both cards yielded similar results, if not worse.
14) As for Quake Live cfg settings, I've tried a lot, but here's what I can remember atm: cg_nopredict 0, post processing is also off. Tried several different resolutions all the way down to 640 x 480, same laggy results.
I'm sure I'm missing some things but hopefully this will be enough for now. As I said, I've tried quite a bit and I'm reaching that point where I don't really want to play anymore. This is an older game that doesn't require that much power to run smoothly. My system is fairly fast, yet this game runs like trash. My Internet connection is packet-loss free, and I generally ping 20-35, yet it feels like I'm pinging 150-200+. I suspect that this issue has to do with Windows 7 x64 or my GFX card (AMD HD 7850). I really don't think it's necessary that I have to buy an NVIDIA based card just to get this game to run as it should. Maybe I'll pick up a cheap NVIDIA, but I know a lot of players use ATI or AMD based GFX cards and run QLive without issues. I really don't want to have to install Windows XP just for this one game, either. At one point, I did mess around on QLive on a fairly old system without this video-lag issue.
Any help will be much appreciated! Suggestions?
