icebreakr 3159 Posted January 27, 2010 Speaking of GFX bugs, will BIS fix that alpha bug, when you look at object with smoke behind the white dots appear on the edge. Share this post Link to post Share on other sites
ModeZt 0 Posted February 5, 2010 Stargun said: Personally I can't mention any other game nowadays where z-fighting became such obvious as in ArmA II. Ha-ha-ha. Just found the same z-fighting in Mass Effect 2 (Presidium level of the Citadel) So yeah it's pretty annoying sometimes, but even the super-top games with uber budgets and huge quality assurance departments suffer from it.

no use for a name 0 Posted February 5, 2010 I get Z-fighting in EVERY GAME I've played...it's not just Arma. Fallout 3, GTA 4, Oblivion, STALKER, and even saw a little in COD: MW2. The only difference is it's not as prevalent in those other games (probably because of the shorter view distances). People need to stop blaming BIS and look at Nvidia/ATI to fix their shit Share this post Link to post Share on other sites

And if everything will go in this way that people trying to "familiarize" with the engine without any "personal" answer from BIS then I will NOT be a returning customer. Or to be precise I will: I will RETURN this game to have a massive REFUND. I'm getting tired of spending countless hours for setting the possible graphics settings to eliminate all of this bugs. Maybe it does not worth it. I'm sorry, it was a good try, BIS! :( Good luck on your "massive" REFUND bye bye Share this post Link to post Share on other sites
Rexxenexx 0 Posted February 6, 2010 Got two questions to ask: Nazul said: Try PROPER game tweaks to ease some of this LOD switching. http://dev-heaven.net/projects/show/proper-projects Theres a thread in the 'addon/mods complete" subsection of this forum. 1. Can someone do a before and after fraps with that mod? 2. Does anyone play this game with a Quadro video card? If so do you have this problem? Share this post Link to post Share on other sites
Leopoldo 10 Posted February 9, 2010 I get this also and it can cause crashes. If i look at a distant village with buildings sometime i can start to get this "flickering" where textures turn white, if i am zoomed in (like with binoculars) it can start to get progressively worse quickly before things just get so crazy the game crashes. Same thing can happen in helicopters or if i am using the UAV and i zoom in on a location. Share this post Link to post Share on other sites

Sintacks 10 Posted May 18, 2010 zachanscom said: untouchable my ass. crysis and uncharted 2 already beat it by a mile. Yeh those games do look good but they both have completely different jobs to do. One is a console game which can't really be compared. Both don't have completely open worlds either. Share this post Link to post Share on other sites
Flash Thunder 10 Posted May 18, 2010 zachanscom said: untouchable my ass. crysis and uncharted 2 already beat it by a mile. Zach since you state alot of BS, why dont you go learn how a z-buffer works then you can come back and compare Arma 2's z-buff to some console game. Z-fighting usually only happens at distance, the z-buffer doesnt know which one to render so they're both escentially rendered which cause an overlap which causes the end result "flickering" Also this is one issue with 3D rendering it happens in many games, games that have shorter viewdistance have less to render/buff etc, which is why they tend to not have any to little z-fighting. .....

no use for a name 0 Posted May 18, 2010 (edited) I noticed that it pretty much happens in all games; the bigger the game world and the further the draw distance, the worse it is. Oblivion had it, Fallout 3 has it, Far Cry 2 had it...I bet even crysis has it when you're up on the highest point looking at very distant objects (although I'm not sure how far the draw distance is). I've even seen it in LOMAC when flying at altitude and zoomed in with the Shkval. Maybe they can tweak the textures or something so it's not as drastic; but I don't think it can ever really be fixed.

PanzerV 10 Posted October 6, 2011 I'm sorry for resurrecting this old thread, but this problem bothers me since OFP 1.46. And I've still got no solution to make the scope/zoomed view even a little better. I think something have to be done with this flickering at least in ArmA III.

Rexxenexx 0 Posted October 7, 2011 I actually still have the problem. BF3 Beta with the Beta Nvidia Drivers has the problem to. Rage doesn't have this problem. Share this post Link to post Share on other sites
ryfle 10 Posted October 18, 2011 I think this is likely due to LOD shifting and Z-fighting. Of course, I couldn't see your video because it said "user removed this content". I experience some flickering time to time. I usually see it when I zoom in with my gun sights. What causes it is the way LOD (Level of Detail) works for game geometry. FYI, a game as big as ARMA can't simply render "brute force", meaning to draw every model in the world at full detail (rendering all triangles). That would destroy frame rate. So game developers create copies of each mesh which are simplified, and reduce the amount of triangles as much as possible. These are called levels of detail. When the camera is far away from a model, it will render a very low poly version with low-res, mip-mapped textures. As you get closer to a model, it's switched out with higher and higher poly versions until you're right up to it -- then the maximum detail model is switched in with hi-res textures. Unfortunately, it's hard to do this smoothly so most big games will have somewhat noticeable LOD shifts; especially when one zooms in or moves through the world quickly. Z-fighting can also cause or exacerbate flickering. It happens because 3D rendering engines have to write values to an array/texture to remember the depth of each pixel. If two objects have a depth (distance from camera) that is very close, you can run into a problem. 32-bit floating point integers simply aren't very precise... we only have 32-bits to represent numbers in binary. So as you can imagine, you won't always get precise results when dealing with something like 0.0034884500348234f * 0.23488324599434. Precision will be lost, and results only semi-accurate. This can cause pixels for two or more objects to have almost the exact same depth value. Let's say there's a box in front of a bush, far away from the camera. In one frame, the game may correctly draw the box pixels over the top of the bush. But in the next frame, it may draw the bush last and overwrite the pixels of the box which should actually occlude the bush. These are two things which can cause odd flickering in games... especially big games with huge, free-roam terrain like ARMA. Different graphics cards handle it better than others too. And your graphics settings (e.g., detail and view distance) can also have an effect on it. You may want to experiment with the game's graphics settings and make sure your video card has the proper settings and up-to-date drivers. This problem doesn't really affect me. I only notice slight LOD flickers when I zoom in. I'm running a custom machine I built from scratch: Windows 7, Intel i7 Quad 64-bit, 12GB RAM, GTX-580 GPU...
