OK. All in all, I can play demanding games with satisfactory settings and framerates (for example, Modern Warfare 2 is maxed out at 1280x1024 with 2xAA or 0xAA, not sure). I first noticed the problem in Crysis. I was playing on a High/Very High setting combination, and I was near a small encampment. On the ground was a flare with red smoke. After I killed the guards, I tried to casually walk across the smoke, and the game suddenly started lagging. I decreased the settings, it happened again. Even on older games, it happens when I go through particles (I hope what I'm describing is really called particles!!!) and to be more specific:
- Rain/Fountains/Water Splashes
- Near explosions
- Other particle effects, like magic, shockwaves etc.
I even tried to play COD4: Modern Warfare on Low settings and low resolutions with no antialiasing, and when I go through smoke grenades, I'm lagging - and it's more intense when I use Smooth Smoke Edges. What's strange is that I could go through smoke in my old computer (on the same game) which had far inferior specs (single core at 2.44 GHz and 768MB RAM, need more...? ) and have no problem...!
The reason I posted this is because of Metro 2033. I spent a good half hour to tweak the settings so it's not a slideshow, I played a while, and when I got out in the open and there is this ashstorm/snowstorm/whatever-storm, I lagged terribly... I don't think it's the open world that poses a problem, because Fallout 3 played great on max settings (and all other open world games I've tried). With my minor hardware experience, I suspect it's the graphics card problem...or something software related.
OK so there was the problem. I apologize if anything was misleading or not that clear; if so, ask and I'll post more info. I know I should've tried to solve it since I saw it, but I never found the time to sit down and give it my attention. Don't get me wrong, I'm fairly experienced in computers generally, but this really puzzled me! Thanks for your help in advance
