Does anyone know any possible issues that can cause HQ rendering to lag? At home my internet connection is fine (20mb download, 1mb upload, 5ms ping) and my computer is more than powerful enough (i7 920 @ 2.66ghz, 12gb DDR3-1600, MSI Radeon 5870 1gb etc) yet if I select high quality rendering it lags like a mofo.
Yet at work, on a computer not even quarter the speed, without a graphics card, on a worse internet connection, I can use HQ rendering fine?
Is there some kind of program in windows 7 or something specific in my graphics card settings at home that might be causing this?

its not you, the viewer lacks hardware acceleration atm and this causes it to run slow. I think its due to be improved in future updates.

I'm sorry I'm a little unsure what you mean. Are you saying it's normal that it doesn't work on a good computer, but works on a computer that is much slower?
Computer at home - i7 920 @ 2.66ghz, 12gb ddr3-1600, MSI Radeon 5870 1gb - Internet speeds 20mb download, 1mb upload, 5ms ping
HQ rendering lags and stutters like crazy.
Computer at work - Core2duo @ 2.0ghz, 2gb ddr2-800, no graphics card - Internet speeds 14mb download, 1mb upload, 15ms ping
HQ rendering works perfectly.

Meaning it won't run well on any computer, regardless of specs, unless you can enable hardware acceleration.
It was enabled during the beta but resulted in black screens for a lot of people, even though on a few computers it allowed a huge performance gain. It was taken off again because it didn't work for everyone.
As it stands, HQ rendering isn't really usable at full screen resolution but works okay in a small-ish window.

Ah, right! I get you, thanks for the confirmation Jack.
That could explain it then. My screens at home are 24" 1920 X 1080 screens where as at work I'm using a tiny 15" 1024 X 768 monitor.

Weird, I can't say I've noticed any problems at all with the 2D Viewer on high quality on either of my machines running it full screen at high resolution. While I'm thinking about it, I have to select HQ, full detail lap charts, weather effects etc. every time that I open the 2D viewer, any chance it can save your preferences from the last time?
Jason Lee medal 5000 12 years 169 days ago
Yeah that does solve the problem. Just went and spectated a race. I can run HQ rendering in a small window, and I can make that window about 75% size of my 1920 X 1080 screen before it starts lagging.

When I said not useable at full screen, that was probably misleading. I'm running 1920x1200 (similar to Grant) so can't personally run it fullscreen + HQ, but perhaps on smaller screen resolutions it behaves better.
As for saving preferences, that has been on the drawing board for a while and I'm not sure how high it is on Andrew's priority list at the moment for viewer updates. Our top priority this last week or two has been resolving the unexpected downtime issues, which has an unfortunate side-effect of delaying new feature implementations.
