<p>Sorry, I know this is a very very old post. Just wanted to post my latest findings.</p>
<p>I recently bought at new laptop - Core i7, 8GB ram, Windows 7 64 bit, good graphics, full hd screen etc... I would have thought it would do slide transistions in a jiffy, but it doesn't. So I tried various things to figure out what was >my< problem. </p>
<p>What helped me (besides keeping the background image at a resonable size, as discussed earlier) is also to keep the resolution of the projector/output monitor at a "low" resolution.For me running the output display at full hd (I know insanely high) would give very slow slide transistions for me. When I decreased the output resolution to something near 1024x768 or similar, everything went smoot. I guess if running openlp without an external monitor, it defaults the output resolution to the your primary screens resolution?</p>
<p>If I just had connected my pc to a projector in the first place, instead of just playing around at home, it would have worked straight out of the box. So if someone is playing around with openlp at home, with only one screen and they are using a high screen resolution (like 1080p), I guess they will see slow transistions? (I am not sure though if openlp would run faster in a 32 bit version of Windows 7?)</p>
<p>This also makes sense to me, since TRB413? above mentioned that rendering is what is causing all the delay, and rendering at a higher resolution would obviously cause more delay.</p>
<p>UPDATE:Font size also have a huge influence on rendering time, especially with outline selected (which I always use).</p>
<p>Anyone experiencing the same?</p>
<p>Just my 50 cents (again),Mads</p>
