April 1, 201511 yr I have a 4 month old GTX660 3Gb card I purchased specifically for P3D2.4. I get occasional brief terrain spiking but I can live with that. I installed 2.5 and it was much worse. I did notice that the card is running in the mid 50C range, and low 40s when running FSX. Do I have a bad card?

April 2, 201511 yr I saw this with FSX when running an 8800GT-OC. In my case, it was simply the video card not being able to process the graphics data from the CPU fast enough. I upgraded my old computer to a 560Ti-SOC and the spikes went away. My computer: ABS Gladiator Gaming PC featuring an Intel 10700F CPU, EVGA CLC-240 AIO cooler (dead fans replaced with Noctua fans), Asus Tuf Gaming B460M Plus motherboard, 16GB DDR4-3000 RAM, 1 TB NVMe SSD, EVGA RTX3070 FTW3 video card, dead EVGA 750 watt power supply replaced with Antec 900 watt PSU.
