Hi, my system has been as follows until 2 days ago: Intel Board DZ68DB, 650 W power supply, Processor Intel i7-2600 CPU @ 3,40GHz, RAM Kingston 16 GM, 1 Intel SSD 224 GB (System), 1 Intel SSD 450 GB (Flightsim), 1 WD HD (Work), Graphics Adapter Zotac, 560Ti, 2GB VRAM, Win 7/64. That's what I would call a middle-class system today. It's for 95 % work and 5 % flight simulation (would love to see it the other way round...) After the fan bearing of the Zotac card became worn out I decided not to repair it, but get a new EVGA Nvidia 760, overclocked, 4 GB VRAM card. Let's come to Flight simulation. I run Prepar3dv1.4 and v2.0. I'll concentrate on 2.0 here. In a certain start situation (ORBX AUS Sydney on active runway) I got 18 fps before replacing the graphics adapter. This is with pretty high settings (Autogen, Scenery Density maxed - which I know ORBX does not suggest), LOD 4.5, Textures 1024, Water at maximum, a few shadows on, HDR off, Bathymetry off, Framerate unlimited, Vsync off, MSAA 4, Trilinear, Tesselation on. I use one Monitor in 1920x1080x32 for simming. No NI settings (reset game settings to default in driver a time ago). Before replacing the card I de-installed the graphics drivers and deleted the shader cache and the corresponding [DISPLAY.Device] entry in the Prepar3d.ini for both simulators. After inserting the new card and installing most recent Nvidia drivers I was amazed to see exactly the same 18 fps on Sydney runway. Actually, I should not complain, after takeoff fps go into the 20's, this is dense scenery, it actually looks quite stunning, as I said, settings are certainly on the high side. Overall I enjoy a quite fluent ride with very few stutters, if any at all. I just expected fps to raise. The new EVGA card is reported on comparison charts as having 30-50 % more performance on essential parameters. I did not expect a fps boost of 50 % of course, but rather something like 10-20% should have shown up. Obviously the graphics adapter is not the bottleneck in the system. At least Windows performance index says otherwise, though. It was 7.3 before the upgrade with the graphics adapter as the limiting component. Graphics adapter performance (and this way the combined index) rose to 7.6 with the new card. Only difference I noted, I had occasional spikes/flashes with the old card (not VAS related, I checked VAS usage), maybe the adapter got too hot after some time. These seem to have been gone after replacement. Anyone with a similar / different experience? Anyone to comment on this? I did not expect a fps boost in Prepar3d1.4 being CPU bound, but wasn't I told 2.0 being much more GPU oriented which should pay off? Thanks for considering and kind regards, Michael
