All thru Beta and up to Patch 2 I had minimal problem with stutters or screen freezes. Since Patch 3 I've had MAJOR problems the first 30 minutes after I log on with screen freezes. I don't call them stutters, they last too long to be a stutter.
They typically happen just as I close under 600 on an enemy plane type I haven't been close to since I logged on. My plane freezes in midair for up to 8 seconds! When it starts up again the enemy plane is now somewhere behind me D 2.5.
And Lord help me if I'm near the ground. When the screen unfreezes I'm typically 1/4 second from an auger.
New maps make it even worse, or at least it seems to. When I logged on for the first evening of Mindanao, I was totally frustrated. I couldn't get near an enemy plane without freezes. After 45 minutes of frustration, it finally goes away, but too many missed kills and ground augers to make it worth it.
I found a work around that helps. When I log on, I find an air base that is extremely active. I jump in a mannable field ack as close to the runway as possible. Aim the ack at the closest place that planes fly by, then AFK to my deck for a couple of beers. I let my absent ack man deal with all the screenfreezes each time a new plane type or skin goes by. Thirty minutes later my video memory used has climbed from 28 MBs to 70 and screen stutters/freezes are almost all gone.
This is especially good if there are some GVs around. Otherwise the first time you dive on a GV for an attack, when the GV loads you get a screen freeze. Since you are pointed towards the ground when you freeze.....insta death! So now I've learned to make my first pass at GVs while flying level just above them so the inevitable first skin load won't kill me.
Once all the planes are cached, my system works great. No complaints about FPS or anything once the freezes are over with.
I agree with Mugzee, the load skins as you need them is a major handicap. Some other system needs to be used.
One possible solution, have an optional button that I can hit after I log on that loads all the planes, GVs, and skins at once. Even if it takes 3 -4 minutes, that's far better than frustrating attacks and pointless deaths because of the current screen freeze method.
Celeron 1.4, 384 RAM, FX-5200 Ultra, Win 98se, Sounblaster Live DX-9 sound acceleration 3/4.
I've tried DX-9 Sound acceleration set to Full, 3/4, and 1/2 (Basic). The sound acceleration has no effect one way or the other with my screen freezes.
I also defrag my computer Hard Drive after each patch or new map load. It doesn't help.
