• Crysis artifacting and glitching.
    7 replies, posted
So, I went to play some Crysis today, and found that there was some major artifacting going on, sometimes extremely bad in some areas, and some areas almost completely fine. For example, for the most part, outdoors in the jungle, everything's fine, though there still is a little artifacting its at the bottom of the screen and is unnoticable. Then some area inside the little miny shacks, things get bizzare, like artifacts everywhere, rendering goes nuts, as in, light is completely drawn wrong, and there's some really fucked up DOF distortion and glitches, which is bizare, because I turned DOF off in the System.cfg file. Temps are fine (after a full hour of playing temps go to around 55 C for both the GPU and CPU), I tried resetting my CPU's clock rate to default, which actually did cure a lot of artifacting outdoors in Crysis. This happens in no other game, Gmod, HL2, Oblivion, UT3, all run fine without any artifacting or glitches. I do use Ati Tray Tools, but I disabled and uninstalled the low level driver it uses, without any difference. Drivers are up to date. Specs: Phenom 2 X3 Radeon 4850 1GB 3GB DDR2 800, CAS 4 2 SATA HDD's in RAID0 (stripe) Here's a pic of the worst of problems (note that the box of artifacts at the lower left corner is always present, outdoors or not.) [img_thumb]http://i46.tinypic.com/auh3ya.jpg[/img_thumb] FYI I ran a test using FurMark, 8x MSAA Post-Proccessing, with Xtreme Burn Mode, and average temps were 61 C, so this shouldn't be a temperature related problem.
Come on, at least some theories?
Your computer clearly is not good enough. :v: [editline]02:13PM[/editline] My friend has an ATI card and is experiencing similar issues. Perhaps it is caused by a driver-related error?
Like I said, a few months ago I never experienced these issues, and it was the same computer.
Did your drivers update?
[QUOTE=FreakyMe;19884606]Did your drivers update?[/QUOTE] This problem happens with the 9.12 drivers and the newest ones, 9.13. I opened my case just an hour ago, and found the heatsink wasn't seated properly, so I not only reseated it, but I applied some fresh thermal paste. The problem became less prominent, but its still there, the artifacts will pop in and out every now and again, they usually last 2-3 minutes. [editline]05:32PM[/editline] The weird thing is, temps were reported before I discovered the heatsink problem were still below average, after playing crysis for 45 mins, the temps were 55 CPU, 63 GPU. 55 C for the CPU is pretty good, Phenom 2's can tolerate up to 100 C before Automatic Shutdown, and 64 C for the GPU is within normal temps with a game like crysis. And FurMark will stress components out the most, its meant to stress them as much as possible to see how stable they are. No problems there, Temps hang around 65-66 C FYI, I get good FPS, 40-45 FPS in crysis, so its not as if the hardware is lacking enough power.
That looks like it was caused by the Screen Space Ambient Occlusion or SSAO. [B]GUIDE ON HOW TO FIX IT[/B] 1. Open the console with "~". 2. Turn off SSAO with "r_SSAO 0" 3. Profit.
That did fix some of the weird HDR and DOF glitches, but the artifacting is back, and this time its bad. It covers the whole screen. It has nothing to do with your command, as enableing SSAO again doesn't remove the artifacting. The weird thing is, the artifacting starts immedietly when the game starts now, not after a little while of playing. Other games still run fine, even if they run for hours. Temps are still sub 65 C, so no overheating. I'm starting to think this might be a corrupt installation, maybe a pixel shader is corrupt or something. I'd be grateful if anyone can confirm this as a possibility. Oh yeah, and as an extension to the r_SSAO command fix (in case someone with a similar problem in the future reads this), open notepad and type "r_SSAO 0" (without quotes) on the first line. Save as System.cfg in the Crysis directory (C:\Program Files\Electronic Arts\Crytek\Crysis), make sure its saved as .cfg and not .txt.cfg (you can do so by changing the file type box in notepads Save As menu to All Files). Crysis automatically executes the commands in the System.cfg file before the engine is loaded, as some commands, especially commands that are significant in the rendering processes (such as HDR, SSAO) activate best or require to be executed this way.
