Game-specific artifacting

[don_svetlio]

So - for some odd reason, in WC3 (2002), Chivalry (2010?) and XCOM (2012) I get some artifacting - mostly minor - in Chivalry there's an occasional black thingie that flickers, in XCOM, the only time I could really tell it apart from screen tearing is when I loaded up my old save and played the final cutscene - had black stuff flicker once in a while. WC3 - I just have a bar flashing.

Now - most people would say "dead GPU" or "dying GPU" but my question is, why are games like Witcher 3, Shogun 2, CS:GO, Heroes V. Age of Wonders, Divinity and such fine? I mean, shouldn't it affect every game and even benches/OC testers? I tried TitanFall - used all my VRAM, nothing odd. I tried Valley - it's fine, DX9 and DX11 - both fine. Tried OCCT Error check - 0 errors. Reinstalled drivers, nothing.

Oddly enough - when I ran WC3 in XP compatibility mode it fixed itself.

Is this a corrupt OS or something? I'm literally clueless.

They stress the GPU differently.  Same reason why overclock stability tests can pass everything and then fail in games, or fail in X and not Y.  If your GPU is not overclocked, you might have a problem though.

All stock. Oddly enough - I don't get why it's only in certain games - most are fine and how does it get fixed by compatibility mode?

Compatibility mode?  Hmm?  It's cos different games use different parts of the GPU more heavily than others.  Like I said earlier, different workloads cause different issues just like in overclocking.  Might want to try your GPU on a different PC to see if it happens as well.  Otherwise, a RMA would be wise.

Not sure if it's pronounced enough for RMA - no other PC to try it in - my friends either live far away or have laptops.

Hey, sorry to be bugging you again - but I think I might be overreacting a bit. So - I looked at this video of the ending of XCOM where I noted the "artifacts" but this also has it - looks to probably be falling debris. I guess the Long War mod might have been the reason for the occasional screen tear as V-sync wasn't properly working the base for some reason - Fraps was registering 60-62-63fps

Just watched it, looks like rocks to me

Yep - I guess the mod I use probably breaks V-sync or the game doesn't use it properly since the main reason I even looked at that is in the base menu when going to different facilities I'd occasionally get a stutter and what looks like screen tearing. Fraps was saying 62 fps so probably that.
