I have been experiencing some truly awful framerates in SL (full disclosure: I use the Firestorm viewer). In fact, it's gotten so bad lately that it has to be measured in seconds per frame instead of frames per second. This typically happens in regions where there are ten or more other avatars within my view, or close to it. If there are twenty or more avatars in view, it can get down to about 30 seconds per frame. And it doesn't just slow down Firestorm, either; my entire computer (Running Windows 7 x64) halts--even the mouse cursor! And sometimes, when it finally gets to a usable point, a window pops up telling me that Windows is running slow and recommends to turn off Aero effects (which don't make a difference, of course). Flushing the cache and restarting the viewer can help for a little while, but it doesn't take long before it just gets really bad again. The kicker? This happens even when the graphical settings are on the bare minimum!
Okay, some tech specs about my system. It was a pretty good gaming machine when I built it back in 2009, but clearly SL has changed since then.
CPU: Intel Core i7 920 (2.67 GHz)
Mobo: ASUS Rampage III Extreme
Video: ATi Radeon HD 5870
RAM: 6 GB
HDD: 80GB SSD boot-up drive, several spinning-platter HDDs for games & programs.
I have a decent pool of money I can dip into for upgrading, but I'd rather do only a minimal amount right now; I'm still considering just building a new PC altogether in the near future. My thought is that the first thing I should replace is the video card. I don't mind purchasing a $375 nVidia GTX 970, which seems to be the new hotness as far as bang for the buck is concerned. The question, though, is: will that get rid of this intolerable slideshow that I'm currently experiencing? Or is the fact that things seem to get better after a cache flush mean that I need a bigger/faster hard drive? Or more/better memory?
Please help me to know what I should be spending my money on most here. Thank you.
