I'm really confused by this one, so here it goes. Currently when I use Second Life viewer 2, old school or phoenix viewer, my viewer will periodically go from its normal 34FPS to 0, stay there a second and go back. randomly, mostly when I'm doing anything, still often enough to be annoying when I'm just standing still typing. It seems most frequently when I'm loading my inventory or using a menu. I do not experience any lag, pausing or freezing in any other program while the client is freezing up. I do not experience any issues in other media like portal 2 or WOW, and I've always had my setting turned up very high. This issue is not remedied by updating or rolling back drivers, turning down any Second life settings or updating rolling back direct X. This only started happening after I had a GFX issue where my GPU possibly had been running to to little power. I suspected I needed a new GFX, but it is suspect since everything runs fine, except SL. I am wondering, since the issues seems to happen mostly when using an inventory, typing or loading a menu. If it has something to do with loading 2d and 3d at the same time? I'm fairly boggled at the moment, I'll post my computer statistics below provided by CPU-Z; Motherboard: ASUSTeK M4A77TD Memory: 4096(DDR3) Dual channels CPU: AMD Phenom II X4 965 GPU: Radeon HD 5770 (core: 850 mhz) (Mem 1024MB) Also my CPs seems to bounce between 3415MHz and 804MHz during the FPS drop. I assume cause 0FPS isn't processing much, but who knows O_O I've tried setting the affinity to one processor, enabling and disabling multiple threads, and changing its priority. I'm stumped, at this point I might need to switch out hardware. I'm more concerned with what might be causing ONLY SecondLive viewers to be having this issue, whene very other graphically intence program I run seems fluid and streamed. I can even run WOW and SL at the same time on seperate monitors and wow will run smoothly while SL freezes up randomly as mentioned before.. This only started a week or two ago. Thanks for the help :D Lanny
